Overview
The SN74AS804BN is a catalog logic device manufactured by Texas Instruments, containing six independent 2-input NAND drivers. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from 0°C to 70°C. The component utilizes a standard plastic 20-pin PDIP (N) package. Electrical characteristics include a high-level output current capability of -48 mA and a low-level output current capability of 48 mA. Switching performance under recommended conditions (VCC = 4.5 V to 5.5 V, CL = 50 pF, RL = 500 Ω) specifies a maximum propagation delay time of 4 ns for both tPLH and tPHL transitions.
Feature Summary
- Contains six independent 2-input NAND driver circuits
- Provides high capacitive-drive capability with strong sink and source currents
- Supports operation across the standard commercial temperature range
Applications
- General-purpose digital logic processing
- Boolean function implementation in positive logic systems
- High-speed data routing and signal buffering
Procurement Notes
Verify that the specific orderable part number matches the required package style and temperature rating. Confirm RoHS compliance status and lead finish specifications against current manufacturing requirements. Ensure compatibility with existing board layouts and thermal management strategies before finalizing procurement decisions.
Selection Notes
Select this component when six independent NAND gates are required in a single package. Consider the AS series for higher speed and drive strength compared to ALS alternatives. Verify that the 20-pin PDIP footprint aligns with available PCB space and assembly equipment capabilities.
Part Context
This device belongs to the Texas Instruments 74AS logic family, designed for applications requiring faster switching speeds than standard TTL or LS families. The 'SN' prefix indicates a commercial-grade product, while the '74' designation confirms its alignment with industry-standard pinouts and electrical interfaces for broad interoperability.
Replacement Considerations
The SN74ALS804AN serves as a lower-power alternative within the same functional family. For military-grade requirements covering extended temperatures, the SN54AS804BJ is specified. Cross-referencing datasheets is necessary to confirm pinout compatibility and electrical parameter differences.
