1. General description

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.

2. 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 JESD22-A114E exceeds 2000 V

• MM JESD22-A115-A exceeds 200 V

• CDM JESD22-C101C exceeds 1000 V

• Multiple package options

• Specified from -40 °C to +85 °C
