Quad 2-Input Multiplexer

age. This device can be used to interface 5V to 3V systems

and on two supply systems such as battery back up. This

circuit prevents device destruction due to mismatched sup-

ply and input voltages.

General Description

The VHC157 is an advanced high speed CMOS Quad 2-

Channel Multiplexer fabricated with silicon gate CMOS

technology. It achieves the high speed operation similar to

equivalent Bipolar Schottky TTL while maintaining the

CMOS low power dissipation.

Features

■ High Speed: t_PD= 4.1 ns (typ) at V_CC= 5V

■ Low power dissipation: I_CC= 4 µA (max.) at T_A= 25°C

■ High noise immunity: V_NIH= V_NIL= 28% V_CC(min.)

It consists of four 2-input digital multiplexers with common

select and enable inputs. When the ENABLE input is held

“H” level, selection of data is inhibited and all the outputs

become “L” level. The SELECT decoding determines

whether the I_0xor I_1xinputs get routed to their correspond-

■ Power down protection is provided on all inputs

■ Low noise: V_OLP= 0.8V (max.)

ing outputs.

An Input protection circuit ensures that 0V to 7V can be

applied to the input pins without regard to the supply volt-
