PRELIMINARY DATA

■

HIGH SPEED:t_PD=4.1ns (TYP.) atV_CC= 5V

LOW POWER DISSIPATION:

I_CC=4 µA (MAX.) at T_A=25 ^oC

HIGH NOISEIMMUNITY:

■

V_NIH= V_NIL=28% V_CC(MIN.)

POWERDOWN PROTECTIONON INPUTS

SYMMETRICAL OUTPUT IMPEDANCE:

|I_OH| = I_OL= 8 mA (MIN)

BALANCEDPROPAGATIONDELAYS:

OPERATING VOLTAGERANGE:

V_CC(OPR)= 2V to 5.5V

non-inverting multiplexer. When the STROBE

input is held high, selection of data is inhibited

and all the outputs become low. The SELECT

decoding determines whether the A or B inputs

get routed to their corresponding Y outputs.

PIN AND FUNCTION COMPATIBLEWITH

74 SERIES157

IMPROVED LATCH-UP IMMUNITY

LOWNOISE:V_OLP= 0.8V(Max.)

■

Power down protection is provided on all inputs

and 0 to 7V can be accepted on inputs with no

regard to the supply voltage. This device can be

used to interface 5V to 3V.All inputs and outputs

are equippedwith protection circuits against static

discharge, giving them 2KV ESD immunity and

transientexcess voltage.

DESCRIPTION

The 74VHC157 is an high-speed CMOS QUAD

2-CHANNEL MULTIPLEXER fabricated with

sub-micron silicon gate and double-layer metal

wiring C²MOS technology.

It consists of four 2-input digital multiplexers with

common select and strobe inputs. It is a
