Product data sheet
1. General description
The 74HC1G66; 74HCT1G66 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. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
The HCT device features control inputs with reduced input threshold levels to allow interfacing to TTL logic levels.
2. Features and benefits
Wide supply voltage range from 2.0 V to 10.0 V Very low ON resistance:
45 Ω (typ.) at VCC = 4.5 V 30 Ω (typ.) at VCC = 6.0 V 25 Ω (typ.) at VCC = 9.0 V High noise immunity CMOS low power dissipation Latch-up performance exceeds 100 mA per JESD 78 Class II Level B Complies with JEDEC standards: JESD8C (2.7 V to 3.6 V) JESD7A (2.0 V to 6.0) ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V Specified from -40 °C to +85 °C and -40 °C to +125 °C
