SN74HCT623N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT623N is an octal bus transceiver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features low power consumption, with a maximum ICC of 80 µA. The device provides typical propagation delays of 11 ns and ±6 mA output drive capability at 5 V. Inputs are TTL-voltage compatible with a maximum input current of 1 µA. High-current 3-state outputs can drive up to 15 LSTTL loads. The component utilizes a PDIP-20 package and supports an operating temperature range from -40°C to +85°C.

• Dual-enable configuration provides flexible timing control for asynchronous two-way communication between data buses.
• High-current 3-state outputs ensure robust signal transmission to multiple loads.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous two-way communication between data buses
• Bus latch applications requiring data storage capabilities
• Systems utilizing TTL-compatible logic interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the PDIP-20 tube packaging format. Confirm that the active status aligns with current production schedules. Ensure compatibility with standard through-hole assembly processes. Validate RoHS compliance requirements against project specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring bidirectional octal data transfer with latching functionality. The HCT series ensures direct compatibility with TTL logic levels without additional interface circuitry. Consider the 3-state output isolation features for complex bus architectures where multiple devices share common lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HCT623 family of octal bus transceivers. It shares functional characteristics with other members of the HCT logic family but is distinguished by its specific dual-enable pinout and lock bus-latch feature set. The N suffix designates the plastic dual-in-line package variant suitable for general-purpose prototyping and manufacturing.
