74LVC1G66

Bilateral switch

Rev. 12 — 12 January 2022

Product data sheet

1. General description

The 74LVC1G66 is a single-pole, single-throw analog switch with two input/output terminals (nY

and nZ) and a digital enable input (nE). When nE is LOW, the analog switch is turned off. Control

inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices

as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at control inputs makes the circuit tolerant of slower input rise and fall times.

2. Features and benefits

• Wide supply voltage range from 1.65 V to 5.5 V

• Very low ON resistance:

• 7.5 Ω (typical) at VCC = 2.7 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

• Overvoltage tolerant control inputs to 5.5 V

• Latch-up performance meets requirements of JESD78 Class I

• ESD protection:

• HBM JESD22-A114F exceeds 2000 V

• MM JESD22-A115-A exceeds 200 V

• Multiple package options

• Specified from -40 °C to +85 °C and -40 °C to +125 °C
