CY74FCT2573ATQCT

The CY74FCT2573ATQCT from Texas Instruments is an 8-bit, high-speed CMOS, TTL-compatible buffered latch with 3-state outputs. This component is designed for driving high-capacitance loads, making it suitable for applications such as memory and address buffers.

Key electrical specifications include a maximum clock frequency of 70 MHz, an output sink current (IOL) of 12 mA, and an output source current (IOH) of -12 mA. The operating voltage range is from 4.75V to 5.25V, with a maximum supply current of 200 µA. The propagation delay (tpd) is specified between 5-10 ns, and a specific delay time of 1.5 ns is also noted.

This latch features balanced outputs, damping resistors, and a flow-through pinout. It supports partial power-down operation via the Ioff feature and has matched rise and fall times. The device is ESD protected, exceeding JESD 22 standards for the Human-Body Model (2000 V), Machine Model (200 V), and Charged-Device Model (1000 V).

Packaged in a 20-SSOP (0.154", 3.90mm Width) format, the CY74FCT2573ATQCT is designed for surface mounting. It operates within an ambient temperature range of -40°C to 85°C. The component is classified under the FCT technology family and is fully compatible with TTL input and output logic levels.
