Overview
The SN74AS832BDWRG4 is a hex 2-input OR driver from the Texas Instruments AS logic series, housed in a 20-pin SOIC (DW) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device provides high capacitive-drive capability with a low-level output current of 48 mA and a high-level output current of -48 mA. Switching characteristics include a propagation delay time ranging from 1 ns to 7.5 ns under specified load conditions.
Feature Summary
- Contains six independent 2-input OR drivers performing Boolean functions Y = A + B or Y = A • B in positive logic.
- Features high capacitive-drive capability suitable for demanding bus driving applications.
- Delivers robust output drive currents of ±48 mA to support heavy loads.
Applications
- High-speed digital logic circuits requiring OR gate functionality.
- Bus driving systems utilizing standard TTL or CMOS logic families.
- Industrial control systems operating within commercial temperature ranges.
Procurement Notes
Verify that the ordering suffix 'G4' corresponds to lead-free packaging and RoHS compliance as defined in the manufacturer's documentation. Confirm the specific package variant matches the required PCB footprint. Ensure the component status aligns with long-term availability requirements, as older logic families may have limited production runs.
Selection Notes
Select this component when high fan-out and fast switching speeds are required for OR logic operations. The AS series offers superior performance compared to standard LS or ALS counterparts. Verify that the system power supply remains strictly within the 4.5 V to 5.5 V limits to ensure reliable operation and prevent damage.
Part Context
This part belongs to the SN74AS832B family of hex 2-input OR drivers. It is functionally compatible with other devices in the 74AS series but offers distinct electrical characteristics regarding speed and drive strength. The device serves as a fundamental building block for complex digital logic designs requiring multiple independent OR gates.
Replacement Considerations
Direct replacements include SN74AS832BDW and SN74AS832BN. Verify pinout compatibility and electrical specifications before substitution. Alternative logic families such as SN74ALS832A offer similar functionality with different power and speed profiles.
