The CD74HC4094PWT is a high-speed silicon-gate CMOS 8-stage shift-and-store bus register designed by Texas Instruments. This integrated circuit is part of the HC family, which is well-known for its high noise immunity and low power consumption. The device is particularly suitable for a wide range of digital applications, from consumer electronics to sophisticated industrial hardware.

Key Features

• Logic Type: 8-Stage Shift and Store Bus Register
• Supply Voltage Range: 2V to 6V, making it compatible with TTL levels and suitable for battery-operated devices.
• Output Drive Capability: 15 LSTTL loads, ensuring compatibility with various logic families.
• High On-Output Current: 7.8mA at VCC = 4.5V
• Shift Frequency: Up to 80MHz (typical), which is suitable for high-speed operations.
• Package: TSSOP (Thin Shrink Small Outline Package) with 16 pins, offering a compact footprint for space-constrained applications.

Functional Description

The CD74HC4094PWT features an 8-bit serial-in, parallel-out shift register that also includes a storage register and 3-state outputs. Data is shifted on the positive-going transitions of the shift register clock input (SH_CP). The data in the shift register is transferred to the storage register when a high logic level is applied to the storage register clock input (ST_CP). If the output enable (OE) is held high, the outputs of the storage register will be in a high-impedance state, allowing for bus connectivity.

Applications

Thanks to its high-speed operation and compatibility with multiple logic families, the CD74HC4094PWT is an excellent choice for a variety of applications, including:

• Serial-to-parallel data conversion
• Remote control holding registers
• LED displays and signboards
• Data storage and transfer systems
• Automotive systems
• Industrial control circuits

Overall, the CD74HC4094PWT from Texas Instruments is a versatile and reliable component that provides a seamless interface between peripheral and core components in digital systems.
