Texas Instruments SN54LVTH374 Data Sheet
Summary
This datasheet describes the Texas Instruments SN54LVTH374 and SN74LVTH374 octal edge-triggered D-type flip-flops with 3-state outputs, designed for 3.3V VCC operation with 5V tolerant I/O supporting mixed-mode signal environments. The eight flip-flops latch input data on the positive transition of the clock signal. Bus hold circuitry on data inputs eliminates external pullup/pulldown resistors, while Ioff and power-up 3-state features support hot insertion. Output ground bounce is typically und

Frequently Asked Questions
Does this flip-flop support mixed operating voltages?
Yes, it is designed for 3.3V low-voltage operation but can provide a TTL interface to a 5V system environment.
Do I need external pullup/pulldown resistors for the data inputs?
No, the active bus-hold circuitry is included and holds unused or undriven inputs at a valid logic state, eliminating the need for such external components.
How can I set the outputs to a high-impedance state?
Use the buffered output-enable (OE) input. When V is between 0 and 1.5V, the devices enter this high-impedance state during power up or power down.
What low voltage level can I use with an unregulated battery?
The device supports unregulated battery operation down to a minimum of 2.7 V.
