ON Semiconductor MC74VHC138DTR2

The ON Semiconductor MC74VHC138DTR2 is a high-speed CMOS 3-to-8 line decoder/demultiplexer integrated circuit designed to address the requirements of system designers who demand high-performance and low-power consumption from their electronic components. This device is particularly suitable for implementing non-inverting decoders and demultiplexers with three binary select inputs (A, B, and C), an enable input (E), and eight mutually exclusive outputs (Y0 to Y7).

The MC74VHC138DTR2 is fabricated using silicon gate CMOS technology which ensures that this decoder exhibits the low power dissipation of CMOS integrated circuits, combined with the high speed of LSTTL gates. This makes it an ideal choice for a wide range of applications in the telecommunications, computing, and consumer electronics sectors, among others.

Key features of the MC74VHC138DTR2 include:

• High-Speed: Typical tpd of 5.5 ns
• Low Power Consumption: 20 µA maximum ICC at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 28% VCC at VCC = 5V
• Power Down Protection Provided on Inputs
• Pin and Function Compatible with Other Standard Logic Families
• Multiple Package Options: Available in TSSOP-16 and other packages

The MC74VHC138DTR2 operates over a wide voltage range of 2V to 5.5V and includes features such as input hysteresis for enhanced noise immunity and output drive capability of up to 8 mA at the VCC = 5V. Additionally, the device has a balanced propagation delay and transition times, which makes it a reliable choice for critical timing applications.

For ease of use in various design layouts, the MC74VHC138DTR2 is offered in a TSSOP-16 package, which is not only space-efficient but also conducive to automated surface-mount assembly processes. ON Semiconductor's commitment to quality ensures that this decoder meets the stringent requirements necessary for industrial and commercial grade applications.
