Product Overview: 74HCT164D14 from Diodes Incorporated

The 74HCT164D14 is a high-speed Si-gate CMOS device from Diodes Incorporated, known for its robust performance and reliability. This integrated circuit is a part of the 74HCT series, which is compatible with TTL levels and designed to operate at the same speed as low power Schottky TTL (LSTTL). The 74HCT164D14 is specifically an 8-bit serial-in/parallel-out shift register, which is a critical component in digital systems requiring the conversion of serial data to parallel outputs.

This device features two serial data inputs (A and B) that can be configured either for single (A) or dual (B) data input. The shift register is edge-triggered with a positive-edge clock input, which means data is shifted into the register on the rising edge of the clock signal. An asynchronous master reset input (/MR) is also provided to clear the register to a low state, which can be useful in initializing the system or in the event of error conditions.

The 74HCT164D14 operates within a supply voltage range of 4.5V to 5.5V, making it suitable for interfacing with 5V logic systems. It can drive up to 10 LSTTL loads and has the ability to directly drive LEDs or other display elements due to its high current output capability. The outputs are also equipped with bus-hold data retention, which eliminates the need for external pull-up or pull-down resistors.

Diodes Incorporated has packaged this device in a 14-pin SOIC (Small Outline Integrated Circuit) format, which is ideal for space-constrained applications. The compact size and the surface-mount package allow for efficient use of PCB real estate, while also providing ease of integration into a variety of digital systems.

Whether you are designing consumer electronics, automotive systems, or sophisticated industrial equipment, the 74HCT164D14 offers a reliable and efficient solution for your serial-to-parallel data conversion needs. With its high-speed operation, compatibility with existing 5V systems, and compact packaging, this shift register from Diodes Incorporated is an excellent choice for designers looking to optimize their digital circuit designs.
