74HC1G66; 74HCT1G66

Single-pole single-throw analog switch

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.

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: 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
