74LVC2G66

Bilateral switch

The 74LVC2G66 is a dual single pole, single-throw analog switch. Each switch has two input/output terminals (nY and nZ) and a digital enable input (nE). When nE is LOW, the analog switch is turned off. 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 all inputs makes the circuit tolerant of slower input rise and fall times.

Features and benefits

Wide supply voltage range from 1.65 V to 5.5 V
Very low ON resistance:
- 7.5 Ω (typical) at V_CC = 2.7 V
- 6.5 Ω (typical) at V_CC = 3.3 V
- 6 Ω (typical) at V_CC = 5 V
Switch current capability of 32 mA
Overvoltage tolerant inputs to 5.5 V
High noise immunity
CMOS low power consumption
TTL interface compatibility at 3.3 V
Latch-up performance meets requirements of JESD78 Class I
Complies with JEDEC standards:
- JESD8-7 (1.65 V to 1.95 V)
- JESD8-5 (2.3 V to 2.7 V)
- JESD8C (2.7 V to 3.6 V)
- JESD36 (4.5 V to 5.5 V)
ESD protection:
- HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
- CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C and -40 °C to +125 °C
