CY74FCT2573T 8-BIT LATCH

The CY74FCT2573T is an 8-bit, high-speed CMOS, TTL-compatible buffered latch with 3-state outputs that is ideal for driving high-capacitance loads, such as memory and address buffers. On-chip 25-Ω termination resistors at the outputs reduce system noise caused by reflections. The CY74FCT2573T can replace the CY74FCT573T to reduce noise in an existing design..

loads, such as memory and address buffers. On-chip 25-Ω termination resistors at the outputs reduce system noise caused by reflections. The CY74FCT2573T can replace the CY74FCT573T to reduce noise in an existing design. When the latch-enable (LE) input is high, the flip-flops appear transparent to the data. Data that meets the required setup times are latched when LE transitions from high to low. Data appears on the bus when the output-enable (OE) input is low. When OE is high, the bus output is in the high-impedance state. In this mode, data can be entered into the latches. This device is fu.
