Technical Specifications

The PI74FCT534ATQX operates within a supply voltage range of 4.75V to 5.25V. It has a maximum input voltage of 7V and an operating temperature range of -40°C to +85°C. The output drive capability is specified at ±24mA, allowing it to drive heavy bus loads. The device features positive-edge triggered D-type flip-flops with a common clock and output enable control. The output enable control allows the outputs to be placed in a high-impedance state, effectively disconnecting the device from the bus.

The package is a TSSOP (Thin Shrink Small Outline Package) which offers a small footprint and allows for efficient heat dissipation. The device is RoHS compliant, ensuring environmental safety.
