QUAD 2 CHANNEL MULTIPLEXER

PRELIMINARY DATA

■

HIGH SPEED: t_PD= 4 ns (TYP.) at V_CC= 5V

LOW POWER DISSIPATION:

I_CC= 8 µA (MAX.) at T_A= 25 ^oC

HIGH NOISE IMMUNITY:

■

V_NIH= V_NIL= 28% V_CC(MIN.)

50Ω TRANSMISSION LINE DRIVING

CAPABILITY

SYMMETRICAL OUTPUT IMPEDANCE:

|I_OH| = I_OL=24 mA (MIN)

BALANCED PROPAGATION DELAYS:

t_PLHt_PHL

OPERATING VOLTAGE RANGE:

(Plastic Package)

(Micro Package)

ORDER CODES :

74AC157B

74AC157M

It consists of four 2-input digital multiplexers with

common select and strobe inputs. It is a

non-inverting multiplexer. When the STROBE

input is held high selection of data is inhibit and

all the outputs become low. The SELECT

decoding determines whether the A or B inputs

get routed to their corresponding Y outputs.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

V_CC(OPR) = 2V to 6V

PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 157

IMPROVED LATCH-UP IMMUNITY

DESCRIPTION

The AC157 is an high-speed CMOS QUAD

2-CHANNEL MULTIPLEXER fabricated with

sub-micron silicon gate and double-layer metal

wiring C²MOS technology. It is ideal for low

power applications maintaining high speed

operation similar to equivalent Bipolar Schottky

TTL.
