MC74VHC244DWR2

Overview

The MC74VHC244DWR2 is an octal bus buffer manufactured by onsemi, belonging to the 74VHC logic family. It features eight non-inverting channels with three-state outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 2 V to 5.5 V and supports surface-mount installation. Key electrical parameters include a low static current of 4 uA and output drive capabilities of 8 mA for both high and low states. Propagation delay is specified at 11 ns.

Feature Summary

• Provides octal buffering with non-inverting signal transmission
• Features three-state outputs for effective bus line management
• Operates across a wide 2 V to 5.5 V supply voltage range
• Designed for low power consumption with minimal static current

Applications

• Memory module address and data bus buffering
• Clock distribution and buffering circuits
• Control signal routing in embedded systems
• Bidirectional data translation between different voltage domains

Procurement Notes

Verify the specific suffix 'R2' against official manufacturer documentation to confirm exact reel specifications and moisture sensitivity level requirements. Ensure compatibility with RoHS directives if applicable to your assembly process. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring octal buffering with low-voltage operation down to 2 V. The 74VHC series offers CMOS performance with TTL-compatible inputs. Consider the 20-SOIC package dimensions for PCB layout constraints and verify that the 8 mA output drive meets the load requirements of the connected circuitry.

Part Context

This part belongs to the 74VHC244 family of octal bus buffers from onsemi. It serves as a standard interface solution for digital logic applications. The device is distinct from the HCT and VHCT variants due to its broader voltage tolerance and specific propagation characteristics defined by the VHC technology node.
