Overview
The SN74AS804BDW is a catalog logic device containing six independent 2-input NAND drivers manufactured by Texas Instruments. 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 component utilizes a 20-pin Small-Outline (DW) package. Electrical characteristics include a typical propagation delay of 2.6 ns at a capacitive load of 50 pF, with maximum delays of 4 ns under specified conditions. Output drive capabilities reach up to 48 mA for both high and low states.
Feature Summary
- Contains six independent 2-input NAND driver circuits
- Provides high capacitive-drive capability
- Features high-speed operation with typical delay of 2.6 ns
- Supports standard plastic small-outline packaging
Applications
- High-speed digital logic processing
- Memory buffer applications
- Clock distribution networks
- General-purpose logic gating
Procurement Notes
Verify the specific ordering suffix 'DW' confirms the 20-pin SOIC package configuration. Confirm RoHS compliance status and lead finish details via the manufacturer's current package addendum. Ensure the procurement channel sources catalog-grade parts rather than military or preproduction variants. Validate that the received components match the SN74AS804BDW designation exactly.
Selection Notes
Select this component when six independent NAND gates are required in a surface-mount format. The AS series offers higher speed and drive strength compared to ALS alternatives. Verify that the 48 mA output current meets the load requirements. Ensure the 0°C to 70°C commercial temperature range aligns with the system environment.
Part Context
This device belongs to the Texas Instruments 74AS (Advanced Schottky) logic family. It serves as a high-speed alternative to standard TTL logic, providing faster switching speeds and lower power dissipation per gate. The SN74AS804BDW represents the commercial grade version housed in a plastic small-outline package, distinct from the military-grade SN54 variants.
Replacement Considerations
SN74ALS804BDW: Offers similar functionality but with lower power consumption and slower switching speeds.
