PI3B3244

3.3V, Hot Insertion, 8-Bit, 2-Port NanoSwitch

Features

Description

ꢀÎNear-Zero propagation delay

ꢀÎ5-ohm switches connect inputs to outputs

ꢀÎFast Switching Speed: 4.5ns (max.)

ꢀÎUltra-Low Quiescent Power (0.2μA Typical)

Pericom Semiconductor’s PI3B series of logic circuits are pro-

duced using the Company’s advanced sub-micron CMOS tech-

nology, achieving industry leading performance.

e PI3B3244 features a set of 3.3V 8-bit bus switches, which is

pinout and function compatible with the P74FCT244T, 74F244,

and 74ALS/AS/LS2448-bit drivers. Two enable signals (BEn) turn

the switches on similar to the enable signals of the 244. e bus

switch create no additional propagation delay or ground bounce

noise.

à Ideally suited for notebook applications

ꢀÎPackaging (Pb-free & Green):

à 20-pin 150-mil wide plastic QSOP (Q)

à 20-pin 173-mil wide plastic TSSOP (L)
