SN74ABTH18646A Description

Short technical summary and product information.

The SN74ABTH18646A is an 18-channel bus transceiver from Texas Instruments, part of the ABT technology family. It features 3-state outputs, TTL-compatible CMOS inputs, and includes bus-hold circuitry and partial power down (Ioff) for reduced power consumption. The device offers very high speed with propagation delays of 5-10ns.

 

This transceiver is designed for bidirectional bus communication in high-speed digital systems. It operates over a temperature range of -40°C to 85°C, making it suitable for industrial environments. The maximum output sink current is 64 mA, and the maximum source current is -15 mA.

 

The SN74ABTH18646A is available in two package options: a 68-pin LQFP (PM) with 0.5 mm lead spacing and a 68-pin Ceramic Quad Flat (HV) with 0.635 mm lead spacing. The LQFP package measures 12 mm x 12 mm. Standard packaging quantity is 64 units.
