The NXP PC74HCT166P is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. The PC74HCT166P is an 8-bit parallel-load or serial-in shift registers with complementary outputs available from the last stage. It allows for a wide range of applications in the field of digital systems.

Key Features

• Logic Type: 8-bit Shift Register
• Output Type: Complementary
• Supply Voltage Range: 4.5V to 5.5V
• Logic Case Style: DIP
• No. of Pins: 16
• Operating Temperature Range: -40°C to +125°C

Functional Description

The device features an 8-bit serial-in, parallel-out shift register that facilitates serial-to-parallel data conversion. The shift register accepts data serially when the shift/load (SH/LD) input is low, and it accepts data in parallel when SH/LD is high. Data is shifted on the positive-going transitions of the clock (CP). When data is loaded in parallel, the state of the data inputs (A-H) is retained in the internal registers. The maximum clock frequency is typically 100MHz, which makes it suitable for high-speed operations.

Applications

The versatility of the NXP PC74HCT166P makes it suitable for a wide array of applications, including:

• Serial-to-parallel data conversion
• Remote control holding registers
• Data routing
• Instrumentation and test equipment
• Automotive systems
