The SN74LVC1G74DCTR is a versatile single positive-edge-triggered D-type flip-flop designed and manufactured by Texas Instruments. This high-performance, silicon-gate CMOS device conforms to the JEDEC standard no. 7A. It is a crucial component for a wide array of digital applications, including data storage, data transferring, frequency division, and much more.

Operating on a voltage range from 1.65V to 5.5V, the SN74LVC1G74DCTR is compatible with mixed-voltage system environments, making it particularly suitable for battery-powered and low-voltage applications. Its low power consumption and high-speed operation, with typical t<sub>pd of 3.4 ns at 3.3V, make it an efficient choice for modern electronic designs.

The device features a set (SD) and reset (RD) input, which are asynchronous, allowing the user to set the output to high or low without the need for a clock signal. This feature is particularly useful in safety-critical applications where the output state must be controlled immediately, regardless of the clock input condition.

The SN74LVC1G74DCTR comes in a small 8-pin SSOP (DCT) package, optimizing board space without compromising performance. Its pinout is designed for easy PCB layout, with the possibility of routing VCC and GND on the top layer, enhancing signal integrity and reducing noise. The inputs can tolerate voltages up to 5.5V, even when the device is powered off, providing additional flexibility and protection in mixed-voltage environments.

Additionally, the device supports the bus hold feature on the data input, which eliminates the need for external pull-up or pull-down resistors and helps maintain last known state during a high-impedance condition. This feature is beneficial in multiplexed bus systems where the data line needs to be held stable during periods of non-drive.

Texas Instruments ensures that the SN74LVC1G74DCTR meets the stringent requirements of the industrial temperature range of -40°C to 85°C. The device is also RoHS compliant and is designed for lead-free soldering, adhering to environmental standards for electronic components.
