Latches datasheet and documents for 74ALS993NT
Latches Overview
The 74ALS993NT is a 9-bit D-type transparent latch manufactured by Rochester Electronics, LLC. It features read-back capability and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes a 28-pin plastic DIP package and supports through-hole mounting. It functions as a single-channel logic component with tri-state outputs, designed for high-speed applications within the 74ALS series specifications.
Latches Feature Summary
- Provides 9-bit data storage with transparent latch functionality
- Includes read-back capability for output verification
- Features tri-state outputs for bus driving applications
Latches Applications
- High-speed digital data buffering
- Parallel-to-serial conversion interfaces
- Memory address latching systems
Latches Procurement Notes
Verify manufacturer origin as Rochester Electronics, LLC, a distributor of excess stock components. Confirm package integrity and pin compatibility before integration. Check RoHS status and moisture sensitivity level requirements for your assembly process. Ensure the part number matches the specific 9-bit configuration required for your design.
Latches Selection Notes
Select this component when a 9-bit width is specifically required, as standard variants often offer 8 or 10 bits. The ALS technology provides faster switching speeds compared to standard LS logic. Verify that the 28-pin DIP package fits your PCB layout constraints and that the tri-state output drive current meets your load requirements.
Latches Part Context
This component belongs to the 74ALS (Advanced Low-power Schottky) family, known for improved speed over standard TTL. Rochester Electronics supplies these parts as surplus or obsolete inventory. The 9-bit configuration distinguishes it from common 8-bit equivalents, requiring specific pin mapping in circuit designs.
Latches Replacement Considerations
Direct substitutes may include other 9-bit ALS latches with identical pinouts. Verify functional equivalence regarding propagation delay and output drive strength. Alternative packages such as SOIC or PLCC may require adapter solutions if surface mount is preferred.
