SN74CBT3126PWR Description

Short technical summary and product information.

The SN74CBT3126PWR is a quadruple FET bus switch from Texas Instruments, featuring independent line switches. Each switch is disabled when its associated output-enable (OE) input is low. This device offers a bandwidth of 200 MHz and supports input/output voltages from 0V to 5.5V.

 

Key electrical specifications include a typical on-resistance of 5000 mΩ and a maximum on-resistance of 22000 mΩ. The operating temperature range is -40°C to 85°C, with a maximum continuous input/output current of 128 mA. The device has 4 independent circuits, each configured as 1:1 SPST.

 

Packaged in a 14-TSSOP, the SN74CBT3126PWR is designed for surface mount applications. It supports single supply voltage and has TTL-compatible input levels. Latch-up performance exceeds 250 mA per JESD 17. The standard '126-type pinout is maintained for compatibility.
