SN74ABT16841DL

The SN74ABT16841DL is a 20-bit bus-interface D-type latch manufactured by Texas Instruments. This component belongs to the ABT technology family and features TTL-Compatible CMOS inputs and 3-State outputs. It is designed for high-speed applications, with a maximum clock frequency of 150 MHz and a typical propagation delay of 3.2 ns.

The latch operates within a voltage range of 4.5V to 5.5V and supports output currents of up to 64 mA (IOL) and -32 mA (IOH). It is housed in a 56-SSOP package, designed for surface mounting. The device offers features such as flow-through pinout for optimized PCB layout and partial power-down capabilities.

Key electrical characteristics include a maximum supply current of 89000 µA. The operating temperature range is from -40°C to 85°C. The SN74ABT16841DL is part of the Texas Instruments Widebus family, utilizing an EPIC-II B BiCMOS design to reduce power dissipation. It also provides robust ESD protection exceeding 2000 V and latch-up performance exceeding 500 mA.

This component is suitable for various digital interface applications requiring high-speed data latching and buffering. Its design considerations include minimizing high-speed switching noise through distributed VCC and GND pins and a flow-through architecture.
