74LVC1G66
Bilateral switch
Rev. 10 — 7 December 2016
Product data sheet
1. General description
The 74LVC1G66 provides one single pole, single-throw analog switch function. It has two
input/output terminals (Y and 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.
2. Features and benefits
Wide supply voltage range from 1.65 V to 5.5 V
Very low ON resistance:
7.5 (typical) at VCC = 2.7 V
6.5 (typical) at VCC = 3.3 V
6 (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-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Enable input accepts voltages up to 5.5 V
Multiple package options
Specified from 40 C to +85 C and 40 C to +125 C
