Texas Instruments SN54LVTH374 Octal Edge-Triggered D-type Flip-Flops With 3-State Outputs SNJ54LVTH374W

The SN54LVTH374 is an octal edge-triggered D-type flip-flop designed for low-voltage operation at 3.3 V, while also providing compatibility with 5 V TTL systems. It features eight flip-flops that capture data on the positive edge of the clock input, with outputs that can be placed in a high-impedance state via a buffered output-enable (OE) input. This high-impedance state allows for bus driving without significant loading, making it suitable for applications requiring hot insertion. The device supports mixed-mode signal operation, allowing for 5 V input and output voltages with a 3.3 V supply. It operates reliably down to a supply voltage of 2.7 V and includes active bus-hold circuitry to maintain valid logic levels on undriven inputs, eliminating the need for external pull-up or pull-down resistors. The SN54LVTH374 also boasts robust latch-up performance exceeding 500 mA and ESD protection that surpasses JESD 22 standards. With a wide operating temperature range of -55¬8C to 125¬8C, this flip-flop is suitable for various applications, including those in harsh environments. The device is available in multiple package options, including the CF and CFP packages, facilitating integration into different designs.
