Product Description

The PI5C3257 is a 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.

Features

  • Near-Zero propagation delay
  • 5Ω switches connect inputs to outputs
  • Direct bus connection when switches are ON
  • Ultra Low Quiescent Power (0.2μA typical)
    • Ideally suited for notebook applications
  • Pin compatible with 74 series 257 logic devices
  • Packaging (Pb-free & Green available):
    • 16-pin 150-mil wide plastic QSOP (Q)
    • 16-pin 150-mil wide plastic SOIC (W)
    • 16-pin 173-mil wide plasticTSSOP (L)

Product Change Notices

PCN # Issue Date Subject
04-07 2004-04-08 Added them to Hynix’s standard CMOS 0.5 mm, 5 V 1P2M/1P3M process on their 200-mm wafer fab line.
13-04.A 2013-09-06 Amended PCN # 13-04 which states that these packages: TSSOP (L08, L14, L16, L24), SSOP (H20), QSOP (Q16, Q20, Q24), SOIC (W08, W14, W16) and TQFN (ZL72) will be assembled using copper wire. Pericom has changed the business plan and we now intend to use gold wire only for particular products while the rest remains using copper wire.
16-26 2016-10-31 Adding JCET (Jiangsu Changjiang Electronics Technology Co., Ltd) in Suqian, China as an additional supplier for devices in TSSOP, MSOP, SOIC, QSOP packages.
14-11 2014-04-30 Porting some bus switch products from Global Foundry 0.5 micron, 5-volt CMOS process to previously qualified MagnaChip.
10-01 2010-03-18 Adding Changjiang Electronics Technology Co. (“CJ”) assembly facility in China to our qualified supplier list of IC package subcontract manufacturers.
16-12 2016-06-02 Adding two internal assembly and test sites: Diodes Technology (Chengdu) Company Limited (CAT) located in Chengdu, China and Diodes SKE/DSH (Shanghai Kaihong Electronic Co./Diodes Inc. Shanghai) (SAT) located in Shanghai, China.
15-16.A 2015-09-30 Porting from MagnaChip's Fab 2 to Fab 3 and converting some products from Au to Cu wire
16-08 2016-05-20 Update some of our package outline drawing dimensions to align with JEDEC standards (with some exceptions) on few packages to accommodate the POD’s of our existing assembly suppliers and own assembly factories
10-03 2010-06-17 Removal of back mark
13-04 2013-01-24 Copper wire qualification for copper bond wire process for various TSSOP (L08, L14, L16, L24), SSOP (H20), QSOP (Q16, Q20, Q24), SOIC (W08, W14, W16) and TQFN (ZL72) packages at Greatek assembly site.
16-22 2016-10-07 Change the tape and reel quantity multiple for the following package types from 3,000 to 2,500: TSSOP-8, -14, -16 (L), QSOP-16, -20 (Q), MQSOP-8 (UE), SOICP-8, -14, -16 (W) pins
Change the tape and reel quantity multiple for the following package types from 4,000 to 2,500: MQSOP-8, -10 (U) pins
