MC10H334FN

Specialty Logic Overview

The MC10H334FN is a Quad Bus Driver/Receiver with transmit and receiver latches, manufactured by onsemi. It operates within a supply voltage range of -4.94 V to -5.46 V and supports an operating temperature from 0°C to +75°C. The device features a typical propagation delay of 1.6 ns for data-to-output transitions. Electrical characteristics include high output voltages between -1.02 V and -0.735 V, and low output voltages between -1.95 V and -1.60 V. Input currents vary based on logic state and pin configuration, while power supply current remains constant at 161 mA across the specified temperature range.

Specialty Logic Feature Summary

• Integrates transmit and receiver latches that capture information on positive signal transitions when enabled.
• Provides improved noise margin of 150 mV over the full operating voltage and temperature range.
• Bus outputs transition to -2.0 V when the device is disabled via the OE control signal.
• Maintains compatibility with MECL 10K logic standards.

Specialty Logic Applications

• High-speed bus driver/receiver circuits requiring latch functionality
• MECL 10K compatible digital systems
• Voltage compensated logic translation interfaces

Specialty Logic Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm package suffix matches FN for PLLC-20 housing. Check RoHS compliance status as standard versions may differ from G-suffix variants. Validate datasheet revision against manufacturing date codes to ensure specification accuracy.

Specialty Logic Selection Notes

Select this component for applications requiring quad bus driving with integrated latching capabilities. Ensure supply voltage aligns with the -4.94 V to -5.46 V operational window. Consider thermal management for the 161 mA power consumption. Verify interface compatibility with existing MECL 10K logic levels before integration into the design.

Specialty Logic Part Context

This part belongs to the MC10H series of ECL logic devices produced by onsemi. It functions as a specialized translator and driver within the broader logic IC category. The device utilizes a 20-lead Plastic Leaded Chip Carrier (PLLC) surface-mount package designed for reliable operation in industrial temperature ranges.

Specialty Logic FAQ

How does the device handle bus outputs when disabled?

When the Output Enable (OE) signal is high, the bus outputs fall to -2.0 V.

What triggers the latching mechanism?

Information is latched on the positive transition of the Data Latch Enable (DLE) and Receiver Latch Enable (RLE) signals when they are at a low level.
