MC14503BCPG

Overview

The MC14503BCPG is a hex non-inverting buffer with three-state outputs manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18.0 Vdc and supports an ambient temperature range from -55 °C to +125 °C. The device features high current source and sink capabilities, enabling it to drive one TTL load over the full temperature range. It includes two disable controls: Disable A manages buffers 1 through 4, while Disable B controls buffers 5 and 6. The component is housed in a 16-pin PDIP package.

Feature Summary

• Hex non-inverting buffer configuration with three-state outputs for common bussing applications
• High current source and sink capability allowing direct driving of TTL loads
• Dual independent disable controls providing versatile output management

Applications

• Common bussing applications requiring tri-state isolation
• TTL-compatible logic interfacing circuits
• Digital signal buffering with controlled output states

Procurement Notes

Verify that the ordering suffix 'G' corresponds to the lead-free (Pb-Free) package variant as specified in the manufacturer's documentation. Confirm the physical package type matches the required PCB footprint, specifically the 16-pin PDIP configuration. Ensure compatibility with the intended operating voltage range and temperature specifications before finalizing procurement.

Selection Notes

Select this component when a hex non-inverting buffer with three-state functionality is required. It is suitable for designs needing high current drive capabilities to interface directly with TTL loads across a wide temperature range. Consider the dual disable control feature if independent grouping of output states is necessary for system bus management or power saving strategies.

Part Context

This part belongs to the MC14503B series of CMOS logic devices produced by onsemi. It serves as a standard solution for digital buffering tasks where signal integrity and bus isolation are critical. The device is designed to replace specific legacy components such as the MM80C97 and 340097, ensuring pin-for-pin compatibility for existing designs.

Replacement Considerations

The datasheet explicitly lists the MM80C97 and 340097 as pin-for-pin replacements.
