PI3B3253WE集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

描述 Description

Pericom Semiconductor’s PI3B3253 is a 3.3V, Dual4:1 Multiplexer/ Demultiplexer with Hi-Z outputs that is pinout compatible

with the PI74FCT253T, 74F253, and 74ALS/AS/LS 253. Inputs can be connected to outputs with low On-Resistance (5Ω) with no

additional ground bounce noise or propagation delay.

特性 Features

• Near-Zero propagation delay

• 5Ω switches connect inputs to outputs

• Fast Switching Speed: 5.2ns max.

• Ultra Low Quiescent Power (0.2µA typical)

– Ideally suited for notebook applications

• Pin compatible with 74 series 253 logic devices

• Packaging (Pb-free & Green available):

– 16-pin 150-mil wide plastic QSOP (Q)

– 16-pin 173-mil wide plastic TSSOP (L)
