1.General description

The 74LVC2G53 is a low-power, low-voltage, high-speed, Si-gate CMOS device.

The 74LVC2G53 provides one analog multiplexer/demultiplexer with a digital selectinput(S),twoindependentinputs/outputs(Y0andY1),acommoninput/output(Z)andanactive LOW enable input (E). When pinE is HIGH, the switch is turned off.

Schmitt-trigger action at the select and enable inputs makes the circuit tolerant of slowerinput rise and fall times across the entire VCC range from 1.65 V to 5.5 V.

2.Features

sWide supply voltage range from 1.65V to 5.5V

sVery low ON resistance:

x7.5Ω (typical) at VCC=2.7V

x6.5Ω (typical) at VCC=3.3V

x6Ω (typical) at VCC=5V

sSwitch current capability of 32 mA

sHigh noise immunity

sCMOS low-power consumption

sTTL interface compatibility at 3.3 V

sLatch-up performance meets requirements of JESD 78 Class I

TECHNICAL DATA

IN74VHC08 Quad 2-Input AND Gate

IN74VHC08 is high-speed logic IC made by CMOS technology and designed for use in high-performance calculating systems with a wide supply voltage range. As for operation speed, IN74VHC08 can be compared with equivalent bipolar ICs based on Schottky TTL and two times surpasses ICs of IN74НС series. IN74VHC08 tolerates operation under conditions when voltage on input is exceeded up to 7V without affecting characteristics and IC reliability. This possibility allows to use IN74VHC08 in radio-electronic devices for interfacing with supply voltages 5V and 3V, eliminate IC failure under supply voltage source emergency outage. Use of output edge shaping block in the microcircuit allows to reduce noise amplitude of noises when switching outputs into the same state simultaneously. Input and output levels of IN74VHC08 are compatible with CMOS levels
