Pericom Semiconductor’s PI5C3257QE is a Quad 2:1 multiplexer/demultiplexer with three-state outputs that is pinout and function compatible with the PI74FCT257T, 74F257, and 74ALS/AS/LS257. Inputs can be connected to outputs with low On-Resistance (5Ω) with no additional ground bounce noise or propagation delay.
Feature
- Near-Zero propagation delay
- 5Ω switches connect inputs to outputs
- Direct bus connection when switches are ON
- Ultra Low Quiescent Power (0.2μA typical)
- Ideally suited for notebook applications
- Pin compatible with 74 series 257 logic devices
- Packaging (Pb-free & Green available):
- 16-pin 150-mil wide plastic QSOP (Q)
- 16-pin 150-mil wide plastic SOIC (W)
- 16-pin 173-mil wide plasticTSSOP (L)
