Overview
The MC74VHC244DWR2G is an octal buffer and line driver from the VHC logic series, manufactured by onsemi. It features eight non-inverting inputs and outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 2 V to 5.5 V. Key electrical parameters include a high-level output current of -8 mA and a low-level output current of 8 mA. Static current is specified at 4 uA, with a maximum operating supply current of 40 uA. Propagation delay is 11 ns. The component supports surface-mount installation and functions reliably across a temperature range of -40 °C to +85 °C.
Feature Summary
- Provides octal bus buffering with three-state output capability for efficient data transmission.
- Operates over a wide supply voltage range from 2 V to 5.5 V for flexible system integration.
- Features low static power consumption suitable for battery-powered applications.
Applications
- Memory mapping control
- Clock drivers
- Bus-oriented transmissions
Procurement Notes
Verify the specific suffix DWR2G corresponds to the SOIC-20 package and tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure moisture sensitivity level handling procedures are followed during storage and assembly to prevent damage.
Selection Notes
Select this component when an octal buffer with three-state outputs is required for bus-oriented systems. The VHC series offers compatibility with standard CMOS logic levels while supporting lower voltage operation down to 2 V. Consider the 11 ns propagation delay and 8 mA drive strength for signal integrity requirements in medium-speed digital circuits.
Part Context
This part belongs to the MC74VHC244 family of octal buffers and line drivers. It shares the same logical function as other variants in the series but is distinguished by its specific package type and manufacturing revision indicated by the suffix. The device is designed for high-density applications requiring multiple buffered channels in a compact footprint.
Replacement Considerations
Direct substitutes include MC74VHC244DTOR and MC74VHC244DTR from onsemi, which offer identical functionality in compatible packages. Cross-brand equivalents such as SN74VHC244DR from Texas Instruments may be considered if pinout and electrical specifications match exactly.
