The Texas Instruments 74LV138A is a high-speed Si-gate CMOS device that is part of the LV family. This 3-to-8 line decoder/demultiplexer is designed to be used in high-performance memory-decoding or data-routing applications that require very short propagation delay times. Its low-voltage operation and low-power consumption make it ideal for battery-operated and portable devices.
Key Features
- Low Voltage Operation: The 74LV138A operates at a voltage range of 2.0V to 5.5V, which allows for use in a wide array of applications, including those that require low power consumption.
- High-Speed Performance: With propagation delays significantly lower than those of typical CMOS devices, this decoder/demultiplexer is well-suited for high-speed operations.
- Multiple Decoding or Demultiplexing Options: It offers three binary select inputs (A, B, and C), an enable input (E), and eight mutually exclusive outputs (Y0 to Y7), providing versatile decoding or demultiplexing capability.
- Output Capability: The device can drive up to 15 LSTTL loads, which means it can be easily interfaced with older technology standards.
- Power-Down Protection: All inputs can be connected to VCC or GND without risking damage, thanks to the power-down protection feature.
- Hysteresis: Inputs include hysteresis, which increases noise immunity and allows for the use of slow transitioning input signals.
Applications
The 74LV138A is suitable for a variety of applications including, but not limited to:
- Memory decoding or data routing in computers and computer peripherals
- Systems that require high-speed signal distribution
- Battery-powered and portable devices due to its low-power requirements
