Texas Instruments SN54AS374 Octal D-Type Edge Triggered Flip-Flops with 3-State Outputs 5962-9756201Q2A

The SN54AS374 is an octal D-type edge-triggered flip-flop featuring 3-state outputs, designed for driving high-capacitance or low-impedance loads. It is suitable for applications such as buffer registers, I/O ports, bidirectional bus drivers, and working registers. The device captures data on the positive edge of the clock input, with outputs that can be enabled or placed in a high-impedance state via a buffered output-enable (OE) input. This high-impedance state allows for bus line driving without significant loading. The SN54AS374 is characterized for operation over a military temperature range of -55°C to 125°C, making it suitable for harsh environments. It operates with a supply voltage range of 4.5V to 5.5V and supports clock frequencies up to 30 MHz. The device is available in various package options, including plastic small-outline and ceramic chip carriers. The internal structure allows for full parallel access for loading, enhancing its versatility in digital circuit designs.
