74ACT646SC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT646SC is an octal bus transceiver and register featuring 3-state outputs in a 24-lead SOIC package. It supports independent registers for A and B buses, enabling multiplexed real-time and stored data transfers with non-inverting paths. The device operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include maximum output source/sink currents of 24mA and TTL-compatible inputs. Propagation delays are specified at 18.5ns maximum under a 50pF load.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Provides registered bus transceiver functionality with D-type flip-flops for data storage
Supports multiplexed transmission of data directly from input buses or internal storage registers
Features independent registers for separate A and B buses with 3-state outputs

Buffers, Drivers, Receivers, Transceivers Applications

Multiplexed real-time and stored data transfer systems
Octal bus interface circuits requiring registered I/O
Non-inverting data path applications with TTL-compatible inputs

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm package type and tape/reel availability. Confirm RoHS compliance status through official environmental declarations. Ensure the selected variant matches the required operating temperature range and logic family specifications for the target application design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring simultaneous registered and transparent data handling across two octal buses. The ACT series ensures compatibility with TTL logic levels while providing CMOS performance characteristics. Verify that the 24-lead SOIC package dimensions fit the intended PCB layout constraints and thermal requirements.

Buffers, Drivers, Receivers, Transceivers Part Context
