TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

8-Channel Multiplexer (3-state)

The TC74HC251A is a high speed CMOS 8-CHANNEL

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 address input (A, B, C). The selected data appears on two

outputs; non-inverting (Y) and inverting (W). When the strobe

input is held high, both outputs are in the high-impedance state.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

• Output drive capability: 10 LSTTL loads

• Pin and function compatible with 74LS251
