M74HC367B1R

Overview

The M74HC367B1R is a high-speed CMOS hex bus buffer with three-state outputs, manufactured using silicon gate C2MOS technology. It contains six non-inverting buffers: four controlled by enable input G1 and two by G2. Outputs are enabled when inputs are low and disabled in a high-impedance state when high. The device operates within a supply voltage range of 2V to 6V. Key electrical characteristics include a typical propagation delay of 9ns at 6V, maximum quiescent current of 4μA, and symmetrical output impedance with minimum drive currents of 6mA for both high and low states.

Feature Summary

• Hex bus buffer architecture with independent control groups
• Three-state outputs providing high-impedance disable capability
• High noise immunity with defined noise voltage thresholds
• Symmetrical output impedance ensuring balanced signal transitions

Applications

• Data bus buffering applications requiring high-speed performance
• System interface circuits utilizing 5V tolerant logic levels
• Memory address/data bus drivers in computer systems

Procurement Notes

Verify the specific ordering suffix B1R corresponds to the Plastic DIP-16 package configuration as documented in the manufacturer's order codes. Confirm that the component meets the required operating temperature range of -55°C to +125°C for your specific application environment. Ensure static discharge protection requirements are met during handling and assembly processes.

Selection Notes

Select this component for designs requiring high-speed data buffering with low power consumption. The wide operating voltage range supports compatibility with various logic families. Verify pin compatibility with existing 74LS367 footprints if replacing legacy components. Consider the DIP-16 package constraints regarding thermal dissipation and board space availability.

Part Context
