74VHC153 Dual 4-Input Multiplexer74VHC153 Dual 4-Input MultiplexerLogic Symbols IEEC/IECFunctional DescriptionThe VHC153 is a dual 4-input multiplexer. It can select two bits of data from up to four sources under the control of the common Select inputs (S 0 , S 1 ). The two 4-input multi-plexer circuits have individual active-LOW Enables (E a ,E b ) which can be used to strobe the outputs indepen-dently. When the Enables (E a , E b ) are HIGH, the corre-sponding outputs (Z a , Z b ) are forced LOW. The VHC153 is the logic implementation of a 2-pole, 4-position switch,where the position of the switch is determined by the logic levels supplied to the Select inputs. The logic equations for the outputs are shown below.Z a = E a • (I 0a • S 1 • S 0 + I 1a • S 1 • S 0 + I 2a • S 1 • S 0+ I 3a • S 1 • S 0 )Z b = E b • (I 0b • S 1 • S 0 + I 1b • S 1 • S 0 + I 2b • S 1 • S 0+ I 3b • S 1 • S 0 )Truth TableH = HIGH Voltage Level L = LOW Voltage Level X = ImmaterialSelect Inputs (a or b)Output Inputs S 0S 1EI 0I 1I 2I 3ZX X H X X X X L L L L L X X X L L L L H X X X H H L L X L X X L H L L X H X X H L H L X X L X L L H L X X H X H H H L X X X L L HHLXXXHH74VHC153 Dual 4-Input Multiplexer Logic DiagramPlease note that this diagram is provided only for the understanding of logic operations and should not be used toestimate propagation delays.74VHC153 Dual 4-Input MultiplexerAbsolute Maximum RatingsStresses exceeding the absolute maximum ratings may damage the device. The device may not function or beoperable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.Recommended Operating Conditions (1)The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings.Note:1.Unused inputs must be held HIGH or LOW. They may not float.Symbol ParameterRatingV CC Supply Voltage –0.5V to +7.0V V IN DC Input Voltage –0.5V to +7.0V V OUT DC Output Voltage –0.5V to V CC + 0.5VI IK Input Diode Current –20mA I OK Output Diode Current ±20mA I OUT DC Output Current ±25mA I CC DC V CC /GND Current ±50mAT STG Storage Temperature–65°C to +150°CT LLead Temperature (Soldering, 10 seconds)260°CSymbol ParameterRatingV CC Supply Voltage 2.0V to +5.5V V IN Input Voltage 0V to +5.5V V OUT Output Voltage 0V to V CCT OPR Operating Temperature –40°C to +85°C t r , t fInput Rise and Fall Time, V CC = 3.3V ± 0.3VV CC =5.0V ± 0.5V0ns/V ∼ 100ns/V 0ns/V ∼20ns/V74VHC153 Dual 4-Input MultiplexerDC Electrical CharacteristicsAC Electrical CharacteristicsNote:2.C PD is defined as the value of the internal equivalent capacitance which is calculated from the operating currentconsumption without load.

MC74HC157A/D

MC74HC157AQuad 2-Input DataSelectors / Multiplexers

High−Performance Silicon−Gate CMOSThe MC74HC157A is identical in pinout to the LS157. The deviceinputs are compatible with standard CMOS outputs; with pullupresistors, they are compatible with LSTTL outputs.This device routes 2 nibbles (A or B) to a single port (Y) asdetermined by the Select input. The data is presented at the outputs innoninverted form. A high level on the Output Enable input sets all fourY outputs to a low level.

Features•Output Drive Capability: 10 LSTTL Loads

•Outputs Directly Interface to CMOS, NMOS, and TTL

•Operating Voltage Range: 2.0 to 6.0 V

•Low Input Current: 1.0 mA

•High Noise Immunity Characteristic of CMOS Devices

•In Compliance with the Requirements Defined by JEDEC Standard

No. 7A•Chip Complexity: 82 FETs or 20.5 Equivalent Gates

•NLV Prefix for Automotive and Other Applications Requiring

Unique Site and Control Change Requirements; AEC−Q100Qualified and PPAP Capable•These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS

Compliant
