SN74ABT646ADBR Description

Short technical summary and product information.

The SN74ABT646ADBR from Texas Instruments is an octal bus transceiver and register designed for high-speed data transmission. It features 8 channels and supports a supply voltage range of 4.5V to 5.5V.

 

This transceiver utilizes TTL input and output types, offering features such as over-voltage tolerant inputs, partial power-down capability (Ioff), and very high speed operation with propagation delays between 5-10ns. The device provides high-drive outputs with IOL of 64mA and IOH of -32mA. It also includes ESD protection exceeding 2000V (HBM) and 200V (MM), and latch-up performance exceeding 500mA per JEDEC Standard JESD-17.

 

The SN74ABT646ADBR is available in a 24-SSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TA). The device consists of bus-transceiver circuits, D-type flip-flops, and control circuitry for multiplexed transmission of data directly from the input bus or from internal registers.
