74151 Datasheet 8-input Multiplexer

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: 8-INPUT MULTIPLEXER The TTL / MSI SN54 / 74LS151 is a high speed 8-input Digital Multiplexer. It provides, in one package, the ability to select one bit of data from up to eight sources. The LS151 can be used as a universal function generator to generate any logic function of four variables. Both assertion and negation outputs are provided. • Schottky Process for High Speed • Multifunction Capability • On-Chip Select Logic Decoding • Fully Buffered Complementary Outputs • Input Clamp Diodes Limit High Speed Termination Effects CONNECTION DIAGRAM DIP (TOP VIEW) VCC I4 I5 I6 I7 S0 S1 S2 16 15 14 13 12 11 10 9 1 2 3 4 56 I3 I2 I1 I0 Z Z 78 E GND PIN NAMES S0 – S2 E I0 – I7 Z Z Select Inputs Enable (Active LOW) Input Multiplexer Inputs Multiplexer Output (Note b) Complementary Multiplexer Output (Note b) LOADING (Note a) HIGH LOW 0.5 U.L. 0.5 U.L. 0.5 U.L. 10 U.L. 10 U.L. 0.25 U.L. 0.25 U.L. 0.25 U.L. 5 (2.5) U.L. 5 (2.5) U.L.

General Description

The LS151 is a logical implementation of a single pole, 8-position switch with the switch position controlled by the state of three Select inputs, S0, S1, S2.

Both assertion and negation outputs are provided.

The Enable input (E) is active LOW.
