STMicroelectronics M74HC4094YRM13TR Product Overview

The M74HC4094YRM13TR is a high-speed CMOS 8-stage shift-and-store bus register manufactured by STMicroelectronics, a leader in the semiconductor industry. This integrated circuit is designed to be compatible with standard TTL (Transistor-Transistor Logic) outputs and is part of the HC (High-speed CMOS) family, which is known for its robust performance and low power consumption.

This particular device features an 8-bit serial-in/parallel-out shift register with a storage register and 3-state outputs. The registers are controlled by two clock inputs: the shift register clock (CP) and the storage register clock (STCP). Data is shifted on the positive-going transitions of the CP. The data in the shift register is transferred to the storage register when the STCP is activated. The data in the storage register is available at the outputs whenever the output enable input (OE) is LOW.

The M74HC4094YRM13TR is versatile and can be used in a wide range of applications, including but not limited to, driving LEDs, interfacing to buses, and serial-to-parallel data conversion. The device's 3-state outputs allow for connection to external buses, making it an excellent choice for expanding the output capabilities of microprocessors and microcontrollers with minimal pin count usage.

Key features of the M74HC4094YRM13TR include:

• High-speed operation: Typical clock frequency is 25 MHz.
• Low power consumption: 80 µA maximum ICC at 25°C.
• High noise immunity: VNIH and VNIL are equal to VCC x 0.1 and GND x 0.1, respectively.
• Output drive capability: 15 LSTTL loads.
• Multiple package options: Available in surface-mount packages that are suitable for automated assembly processes.

The device is supplied in a compact surface-mount package, specifically the DFN16 (3x3 mm) package, and is identified by the ordering code M74HC4094YRM13TR. This package type is well-suited for space-constrained applications and provides a reliable solution for high-density circuit designs.

With its combination of high-speed performance, low power consumption, and versatile functionality, the M74HC4094YRM13TR from STMicroelectronics is an excellent choice for designers looking to implement efficient data handling and bus interfacing operations in their digital systems.
