PI3B3257A
Overview
Pericom Semiconductor’s PI3B3257A is a 3.3 Volt, 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.
- Near-Zero propagation delay
- 5Ω switches connect inputs to outputs
- Fast Switching Speed: 4.8ns max.
- Ultra-Low Quiescent Power: 0.1µA typical - Ideally suited for notebook applications
- Pin compatible with 74 series 257 logic devices
- Packaging (Pb-free & Green): - 16-pin 150 mil wide plastic QSOP (Q)
