74F368PC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74F368PC is a hex inverter/buffer with 3-state outputs, manufactured by Fairchild Semiconductor and now part of the onsemi portfolio. It operates within a supply voltage range of +4.5V to +5.5V. The device features high-speed performance with propagation delays (tPLH/tPHL) ranging from 1.0ns to 7.5ns at VCC=5.0V and CL=50pF. It provides 3-state outputs capable of sinking 64mA in the low state. The package is a 16-Lead Plastic Dual-In-Line (PDIP), JEDEC MS-001, 0.300 Wide.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity as this device was originally manufactured by Fairchild Semiconductor before acquisition by onsemi. Confirm the specific ordering suffix 'PC' corresponds to the 16-Lead PDIP package. Check for RoHS compliance status relative to the manufacturing date, as original datasheets may predate modern environmental regulations. Ensure the source document matches DS009521 specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select the 74F368PC when a hex inverting buffer with tri-state control is required for high-speed digital buses. Compare propagation delay specifications against system timing requirements, noting the maximum delay of 7.5ns under worst-case conditions. Ensure the design accommodates the recommended operating temperature range of 0°C to +70°C and the 16-pin DIP footprint constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74F series of high-speed TTL-compatible logic devices. It is functionally related to the non-inverting 74F367, sharing similar electrical characteristics and package options. The 74F series was designed to offer faster switching speeds than standard 74LS logic while maintaining pin compatibility.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the difference between the 74F366 and 74F368?

The 74F366 is a hex buffer with non-inverting outputs, whereas the 74F368 is a hex inverter with inverting outputs. Both feature 3-state outputs and identical pinouts.

What does the '3-STATE' designation imply for this IC?

It indicates that the outputs can assume a high impedance state (Z) in addition to high and low logic levels, allowing multiple devices to share a common bus without interference when disabled.
