CBT3257A
Quad 1-of-2 multiplexer/demultiplexer
Rev. 6 — 20 June 2019
Product data sheet
1. General description
The CBT3257A is a quad 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer. The low ON
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 and benefits
• 5 Ω switch connection between two ports
• TTL-compatible input levels
• Minimal propagation delay through the switch
• Latch-up protection exceeds 100 mA per JEDEC standard JESD78 class II level A
• ESD protection:
• HBM JESD22-A114F exceeds 2000 V
• MM JESD22-A115-A exceeds 200 V
• CDM JESD22-C101E exceeds 1000 V
• Multiple package options
• Specified from -40 °C to +85 °C
