PI5C3244

8-Bit, 2-Port Switch

Features:

Description:

• Near-Zero propagation delay

Pericom Semiconductor’s PI5C3244 features a set of eight bus

switches which is pinout and function compatible with the

PI74FCT244T, 74F244, and 74ALS/AS/LS 244 8-bit drivers. Two

enable signals (BEn) turn the switches on similar to the enable

signalsofthe244. Thebusswitchcreatesnoadditionalpropagation

delay or ground bounce noise.

• 5-ohm switches connect inputs to outputs when enabled

•

Direct bus connection when switches are ON

UltraLowQuiescentPower(0.2µATypical)

– Ideally suited for notebook applications

•

Pin compatible with 74 Series 244 logic devices

• Packaging(Pb-free&Greenavailable):

– 20-pin173-milwideplasticTSSOP(L)

– 20-pin150-milwideplasticQSOP(Q)

– 20-pin300-milwideplasticSOIC(S)
