Texas Instruments SN54LVTH374 Octal Edge-Triggered D-type Flip-Flops With 3-State Outputs 5962-9951001QSA

The SN54LVTH374 is an octal edge-triggered D-type flip-flop designed for low-voltage operation at 3.3 V, while also supporting TTL interface levels for 5 V systems. It features eight flip-flops that capture data on the positive clock edge, with outputs that can be placed in a high-impedance state via a buffered output-enable (OE) input. This functionality allows for effective bus driving without the need for external pull-up or pull-down resistors, thanks to its active bus-hold circuitry. The device supports mixed-mode signal operation, allowing for 5 V input and output voltages with a 3.3 V VCC. It operates reliably down to 2.7 V and is specified for hot-insertion applications, ensuring that outputs are disabled during power-up and power-down to prevent backflow current. The SN54LVTH374 also boasts robust latch-up performance exceeding 500 mA and ESD protection levels that surpass JESD 22 standards, making it suitable for a variety of applications requiring high reliability. The operating temperature range is from -55¬8C to 125¬8C, accommodating diverse environmental conditions.
