CBT3257A
Quad 1-of-2 multiplexer/demultiplexer
The CBT3257A is a quad single-pole, dual-throw bus switch. The device features an output enable input (OE) and a select input (S). When OE is LOW the switch is enabled and the select input can be used to connect the nA terminals to either of the associated nB terminals.
Features and benefits
5 Ω switch connection between two ports
Minimal propagation delay through the switch
Direct interface with TTL levels
Overvoltage tolerant control inputs to 5.5 V
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
