1 General description
The 74CB3Q3257 is a quad high-bandwidth single-pole, double-throw FET bus switch. The device Features one select input (S) and one output enable input (OE). The switch is disabled when the OE input is HIGH. An internal charge-pump increases the gate voltage of the NMOS pass transistor. The result is improved RON and RON(flat) performance and the ability to switch 5 V signals when VCC = 3.3 V.
2 Features and benefits
- Wide supply voltage range from 2.3 V to 3.6 V
- Overvoltage switching on switch ports:
- 0 V to 5 V switching with VCC = 2.5 V
- 0 V to...
