Product Overview: CD74HC194PWR by Texas Instruments

The CD74HC194PWR is a high-performance, CMOS logic integrated circuit designed and manufactured by Texas Instruments. This device is a versatile 4-bit bidirectional universal shift register that operates at high speed with the robustness of CMOS technology. It is commonly used in a wide range of digital applications, including computing systems, data storage, and communication devices where the manipulation of digital data is required.

Key Features

• Logic Type: 4-bit Bidirectional Universal Shift Register
• Operating Voltage: 2V to 6V, accommodating a broad range of applications and compatible with TTL levels.
• High Speed: Capable of shifting at a frequency of up to 25 MHz at 5V, ensuring swift data processing.
• Low Power Consumption: CMOS technology ensures low power dissipation which is ideal for battery-powered devices.
• Output Drive Capability: Capable of driving up to 10 LSTTL loads, providing flexibility in interfacing with other logic families.
• Package: Available in a TSSOP-16 (Thin Shrink Small Outline Package) that is suitable for space-constrained applications.
• Temperature Range: Operates within a temperature range of -55°C to 125°C, ensuring reliability across various environmental conditions.

Functional Description

The CD74HC194PWR features four modes of operation: shift right, shift left, hold (do nothing), and load data. The mode of operation is determined by two input control lines. The device includes a master reset input that clears the register setting all outputs low. It also provides true and complementary outputs to increase its utility. The parallel load inputs and flip-flop outputs are multiplexed to reduce the number of package pins.

Applications

Due to its versatile nature, the CD74HC194PWR is suitable for a variety of applications, including:

• Serial-to-parallel data conversion
• Parallel-to-serial data conversion
• Sequential logic operations
• Temporary data storage
• Data manipulation and control systems
