Product Overview: 74AHCT595PW by NXP Semiconductors
The 74AHCT595PW is a high-speed, 8-bit shift register with a storage register and 3-state outputs, designed and manufactured by NXP Semiconductors. This integrated circuit is part of the advanced high-speed CMOS family (AHCT) and is particularly suitable for interfacing with 5 V logic levels. It is designed to have both high noise immunity and low power consumption, making it ideal for a wide range of applications.
The device features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Data is shifted on the positive-going transitions of the shift register clock input (SHCP). The data in the storage register appears at the outputs whenever the output enable input (OE) is LOW. A high on OE causes the outputs to assume a high-impedance OFF-state. The device also features a master reset (MR) input that clears the register, setting all outputs LOW.
One of the key benefits of the 74AHCT595PW is its versatility. It can be used in a variety of applications, including:
- Serial-to-parallel data conversion
- Remote control holding registers
- LED displays and LED signboards
- Register for digital signal processing
The 74AHCT595PW comes in a TSSOP16 (Thin Shrink Small Outline Package) that is not only space-saving but also compatible with standard surface-mount assembly processes. This package is especially beneficial for compact PCB layouts, where space is at a premium.
Key features of the 74AHCT595PW include:
- 8-bit serial input
- 8-bit serial or parallel output
- Storage register with 3-state outputs
- Shift register with direct clear
- Maximum clock frequency of 100 MHz
