Product Overview: 74LCX374MTR by STMicroelectronics

The 74LCX374MTR is a low voltage CMOS octal D-type flip-flop with 5V tolerant inputs and outputs, designed and manufactured by STMicroelectronics. This integrated circuit is part of the 74LCX family, which is known for its high-speed operation while maintaining low power consumption. It is particularly suitable for interfacing with 5V systems in a 3.3V environment.

The 74LCX374MTR features eight edge-triggered flip-flops with individual D-type inputs and 3-state outputs. These flip-flops capture the state of their individual D-inputs on the rising edge of the clock pulse, and the data is available at the Q outputs. The 3-state outputs are controlled by an output enable (OE) input, which allows the user to place the eight outputs in either a normal logic state or a high-impedance state, thus enabling the possibility to connect multiple outputs to a common bus without interference.

Constructed with advanced silicon gate CMOS technology, the 74LCX374MTR offers 5V tolerant inputs, which can be driven from either 3.3V or 5V devices. This feature simplifies the design of mixed-voltage systems and enhances flexibility in board design. The device operates at a voltage range of 2.3V to 3.6V, which allows for low-voltage operation and lower power dissipation, making it ideal for battery-operated and power-sensitive applications.

The 74LCX374MTR comes in a TSSOP-20 package, offering a compact footprint suitable for space-constrained applications. It provides the high-speed performance of LSTTL combined with the true CMOS low power consumption and is specified to operate over a broad temperature range. The device also includes additional features such as bus hold, which retains the inputs' last state whenever the input goes to high impedance, preventing floating inputs and eliminating the need for pull-up or pull-down resistors.

Overall, the 74LCX374MTR is a versatile and reliable component for use in a wide range of applications, including communication interfaces, data storage, industrial controls, and consumer electronics. Its compatibility with both 3.3V and 5V systems, along with its power efficiency, makes it an excellent choice for designers looking to create robust, interoperable, and energy-efficient electronic products.
