STMicroelectronics M74HC148M1TR 8-to-3 Line Priority Encoder

The M74HC148M1TR is a high-speed CMOS 8-to-3 line priority encoder designed and manufactured by the renowned semiconductor company, STMicroelectronics. This integrated circuit is part of the HC family, which implies that it combines silicon-gate CMOS technology with TTL-compatible inputs, providing the best of both worlds in terms of speed and power consumption.

With its ability to encode eight input lines to three outputs, the M74HC148M1TR simplifies the process of reducing multiple inputs into a smaller number of outputs for subsequent processing or display. Its priority encoding ensures that the highest-order data line is represented at the output, making it ideal for a variety of applications such as data multiplexing, alarm systems, and microprocessor interfacing.

The device features an inverted output (Y0 to Y2) and an active low enable input (EI), which allows multiple encoders to be cascaded for handling more than eight input lines. The active low enable input ensures that the device is operational only when the EI pin is held low, allowing for efficient power management and system design flexibility.

The M74HC148M1TR is offered in the TSSOP16 package, a compact surface-mount package that is well-suited for space-constrained applications. Its operating voltage range of 2V to 6V allows for compatibility with a variety of logic levels, making it a versatile choice for designers working across different voltage domains.

Key features of the M74HC148M1TR include:

• 8-to-3 line priority encoding
• High-speed operation
• Low power consumption
• Cascadable for n-bit encoding
• Standardized symmetrical output characteristics
• Complies with JEDEC standard no. 7A
• ESD performance: HBM > 1 KV; MM > 200 V
