SN74CB3T3257PW Description

Short technical summary and product information.

The Texas Instruments SN74CB3T3257PW is a versatile 4-channel, 2:1 (SPDT) FET bus switch designed for low-voltage applications. It operates with a VCC range of 2.3V to 3.6V and supports mixed-mode signal operation, allowing 5V input signals to be translated down to 3.3V or 2.5V outputs.

 

This device offers a bandwidth of 100 MHz and features low on-state resistance (5Ω typical) with minimal input/output capacitance (5pF typical off-state). It supports bidirectional data flow with near-zero propagation delay and includes undershoot clamp diodes on data and control inputs. The SN74CB3T3257PW is suitable for various protocols including Analog, I2C, I2S, JTAG, RGMII, SPI, TDM, and UART.

 

Packaged in a 16-TSSOP, the SN74CB3T3257PW is designed for surface mount applications. It operates within an industrial temperature range of -40°C to 85°C and exhibits excellent ESD performance, exceeding 2000V HBM and 1000V CDM. Its low power consumption (20µA max) makes it an efficient choice for power-sensitive designs.
