Product Overview: 74VHC238MTR by STMicroelectronics

The 74VHC238MTR is a high-speed CMOS 3-to-8 line decoder/demultiplexer integrated circuit produced by STMicroelectronics, a leader in the semiconductor industry. This device is designed to offer high-performance solutions for a variety of digital systems, particularly where low power consumption and high noise immunity are required. It is part of STMicroelectronics' VHC family, which is recognized for its robustness and reliability in demanding applications.

The 74VHC238MTR is capable of converting three binary input signals to eight mutually exclusive outputs. The device features three enable inputs, two active-low (E1, E2) and one active-high (E3). The decoder function is enabled when E1 and E2 are held low, and E3 is held high. When the enable conditions are met, the eight outputs (Y0 to Y7) will selectively go low based on the binary value of the three input signals (A, B, C). If the enable conditions are not met, all outputs will remain high.

Key features of the 74VHC238MTR include:

• High speed: t_PD = 8.5ns (typ) at V_CC = 5V
• Low power dissipation: I_CC = 4μA (max) at T_A = 25°C
• Power-down protection is provided on all inputs and outputs
• Pin and function compatible with 74 series 238
• Multiple package options available

The 74VHC238MTR operates over a wide voltage range of 2V to 5.5V, making it versatile for interfacing with both TTL and CMOS logic levels. Its low quiescent current and high immunity to noise make it an excellent choice for battery-operated devices, portable equipment, and other power-sensitive applications.

The device comes in a surface-mount package, specifically in an SO-16L package, which is suitable for automated assembly processes. The "MTR" suffix indicates that the product is provided in tape and reel packaging, which is ideal for large volume production requirements.

With its robust performance and compatibility with industry-standard logic families, the 74VHC238MTR is an excellent choice for designers looking to implement efficient decoding or demultiplexing functions in their digital systems.
