Functional Description

? 8-Channel Multiplexer

General

The 74HC151D is a high speed CMOS 8-CHANNEL MULTIPLEXER fabricated with silicon gate C2MOS

technology.

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power

dissipation.

One of eight date input signals (D0-D7) is selected by decoding of the three-bit address input (A, B, C). The

selected data appears on two outputs: non-inverting (Y) and inverting (W).

The strobe input provides two output conditions; a low level on the strobe input transfers the selected data to

the outputs. A high level on the strobe input sets the Y output low and the W output high without regard to the

data or select input conditions.

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features

(1) High speed: tpd = 15 ns (typ.) at VCC = 5 V

(2) Low power dissipation: ICC = 4.0 μA (max) at Ta = 25 

(3) Balanced propagation delays: tPLH ≈ tPHL

(4) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V
