CBT3257A
Quad 1-of-2 multiplexer/demultiplexer
Rev. 01 — 27 October 2005
Product data sheet
1. General description
The CBT3257A is a quad 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer.
The low ON-state resistance of the switch allows inputs to be connected to outputs
without adding propagation delay or generating additional ground bounce noise.
Output enable (OE) and select-control (S) inputs select the appropriate nB1 and nB2
outputs for the nA input data.
The CBT3257A is characterized for operation from −40 °C to +85 °C.
2. Features
s 5 Ω switch connection between two ports
s TTL-compatible input levels
s Minimal propagation delay through the switch
s ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per
JESD22-A115 and 1000 V CDM per JESD22-C101
s Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA
