74AHC1G66; 74AHCT1G66 Single-pole single-throw analog switch Rev. 04 — 18 December 2008 Product data sheet 1. General description 74AHC1G66 and 74AHCT1G66 are high-speed Si-gate CMOS devices. They are single-pole single-throw analog switches. The switch has two input/output pins (Y and Z) and an active HIGH enable input pin (E). When pin E is LOW, the analog switch is turned off. 2. Features I Very low ON resistance: N 26 Ω (typ.) at VCC = 3.0 V N 16 Ω (typ.) at VCC = 4.5 V N 14 Ω (typ.) at VCC = 5.5 V I High noise immunity I Low power dissipation I Balanced propagation delays I Multiple package options I ESD protection: N HMB JESD22-A114E exceeds 2000 V N MM JESD22-A115-A exceeds 200 V N CDM JESD22-C101C exceeds 1000 V I Specied from −40 °C to +85 °C and −40 °C to +125 °C 3.
