CBT3253A
Dual 1-of-4 FET multiplexer/demultiplexer
The CBT3253A is a dual single-pole,4-throw bus switch. The device features two output enable inputs ( nOE) and two select inputs (S0 and S1). When nOE are LOW the switch is enabled and the select inputs can be used to connect the nA terminal to one of the four associated nB terminals.
Features and benefits
5 Ω switch connection between two ports
Direct interface with TTL levels
Overvoltage tolerant control inputs to 5.5 V
Minimal propagation delay through the switch
Latch-up protection exceeds 100 mA per JEDEC standard JESD78 class II level A
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C
