SN74CB3T3384DBQR Description

Short technical summary and product information.

The SN74CB3T3384DBQR from Texas Instruments is a high-speed, TTL-compatible FET bus switch. It features 10 channels configured as two independent 5-bit bus switches, allowing for flexible system design. The device supports mixed-mode signal operation and provides voltage translation, tracking the VCC supply.

Key electrical characteristics include a wide operating voltage range of 2.3V to 3.6V and low ON-state resistance. The SN74CB3T3384DBQR supports various signaling levels from 0.8V to 5V and is ideal for low-power portable equipment. It also offers features like near-zero propagation delay and 5V-tolerant I/Os.

This bus switch is supplied in a 24-SSOP (0.154", 3.90mm Width) surface-mount package. It operates within an ambient temperature range of -40°C to 85°C. The device is suitable for applications requiring level translation, memory interleaving, and bus isolation.
