General description

The 74LVC1G66 is a low-power, low-voltage Si-gate CMOS device. The 74LVC1G66 provides one single pole, single-throw analog switch function. It has two input/output terminals (Yand Z) and an active HIGH enable input pin (E). When E is LOW, the analog switch is turned off.

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

Features

■ Wide supply voltage range from 1.65 V to 5.5 V

◆ 6.5 Ω (typical) at VCC = 3.3 V

◆ 6 Ω (typical) at VCC = 5 V

■ Switch current capability of 32 mA

■ High noise immunity

■ CMOS low power consumption

■ TTL interface compatibility at 3.3 V

■ Latch-up performance meets requirements of JESD78 Class I

■ ESD protection:

◆ HBM JESD22-A114E exceeds 2000 V

◆ MM JESD22-A115-A exceeds 200 V

■ Enable input accepts voltages up to 5.5 V
