Description

The FCT2373T and FCT2573T are 8-bit, high-speed CMOS TTL-compatible buffered latches with three-state outputs that are ideal for driving high-apacitance loads, such as memory and address buffers. On-chip 25Ω termination resistors have been added to the outputs to reduce system noise caused by reflections. FCT2373T can be used to replace FCT373T, and FCT2573T to replace FCT573T to reduce noise in an existing design.

When latch enable (LE) is HIGH, the flip-flops of FCT2373T and FCT2573T appear trans-parent to the data. Data that meets the required set-up times are latched when LE transitions from HIGH to LOW. Data appears on the bus when the output enable (OE) is LOW. When output enable is HIGH, the bus output of FCT2373T and FCT2573T is in the high impedance state. In this mode, data can still be entered into the latches.

The outputs of FCT2373T and FCT2573T are designed with a power-off disable feature to allow for live insertion of boards.
