CY74FCT823CTQCT

Overview

The CY74FCT823CTQCT is a D-type bus driver manufactured by Texas Instruments, belonging to the FCT logic series. It features nine bits per element with tri-state, non-inverted outputs. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum clock frequency defined by propagation delay characteristics. At 5V with a 300pF load, the maximum propagation delay is 12.5ns. Output drive capabilities include 32mA high-level and 64mA low-level currents. The static current (IQ) is specified at 200µA. It utilizes a master reset function and is housed in a 24-SSOP package suitable for surface mount installation.
