PI3B3244

3.3V, Hot Insertion,

8-Bit, 2-Port NanoSwitch™

Description

Features

• Near-Zero propagation delay

• 5-ohm switches connect inputs to outputs when enabled

• Fast Switching Speed - 4.5ns max.

PericomSemiconductor’sPI3Bseriesoflogiccircuitsareproduced

using the Company’s advanced sub-micron CMOS technology,

achieving industry leading performance.

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

pinout andfunctioncompatiblewiththeP74FCT244T,74F244,and

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

switches on similar to the enable signals of the 244. The bus switch

create no additional propagation delay or ground bounce noise.

• Ultra-LowQuiescentPower(0.2µATypical)

– Ideally suited for notebook applications

• Pin compatible with 74 series 244 logic devices

• Packaging:
