74AHC1G66; 74AHCT1G66

Single-pole single-throw analog switch

The 74AHC1G66; 74AHCT1G66 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. The enable input is overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

Features and benefits

Very low ON resistance:
- 26 Ω (typ.) at V_CC = 3.0 V
- 16 Ω (typ.) at V_CC = 4.5 V
- 14 Ω (typ.) at V_CC = 5.5 V
Wide supply voltage range from 2.0 to 5.5 V
Overvoltage tolerant control input to 5.5 V
High noise immunity
CMOS low power dissipation
Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
SOT353-1 and SOT753 package options
ESD protection:
- HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
- CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Specified from -40 °C to +85 °C and -40 °C to +125 °C
