DESCRIPTION
The 74AC157 is an advanced high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.
It consists of four 2-input digital multiplexer 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.
■ HIGH SPEED: tPD = 4ns (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION:
ICC = 4μA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY:
VNIH = VNIL = 28 VCC (MIN.)
■ 50? TRANSMISSION LINE DRIVING CAPABILITY
■ SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL = 24mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ? tPHL
■ OPERATING VOLTAGE RANGE:
VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 157
■ IMPROVED LATCH-UP IMMUNITY
