QUAD 2 CHANNEL MULTIPLEXER

PRELIMINARY DATA

■

HIGH SPEED: t_PD= 5.5 ns (TYP.) at V_CC= 5V

LOW POWER DISSIPATION:

I_CC= 8 µA (MAX.) at T_A= 25 ^oC

COMPATIBLE WITH TTL OUTPUTS

■

_IH= 2V (MIN), V = 0.8V (MAX)

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 :

74ACT157B

74ACT157M

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.

The device is designed to interface directly High

Speed CMOS systems with TTL, NMOS and

CMOS output voltage levels.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

V_CC(OPR) = 4.5V to 5.5V

PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 157

IMPROVED LATCH-UP IMMUNITY

DESCRIPTION

The ACT157 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.

It consists of four 2-input digital multiplexers with

PIN CONNECTION AND IEC LOGIC SYMBOLS
