Overview
The DM81LS97AN is a low-power-Schottky TTL octal buffer manufactured by onsemi. It features eight two-input buffers with active LOW output enables, providing true data at the outputs. The device utilizes a 20-Lead Plastic Dual-In-Line Package (PDIP). Recommended operating conditions specify a supply voltage of 4.75V to 5.25V and an operating temperature range of 0°C to +70°C. DC electrical characteristics include a HIGH level output current of -5.2 mA and a LOW level output current of 24 mA.
Feature Summary
- Provides eight independent two-input buffers in a single package
- Features active LOW output enable lines for high-impedance control
- Utilizes low-power-Schottky technology for efficient operation
- Presents true non-inverted data at the outputs
Applications
- Data bus buffering applications
- Memory address decoding circuits
- I/O port expansion systems
- Digital signal routing networks
Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the part number matches the specific DM81LS97AN designation. Check datasheet revisions for any updates to electrical parameters or pin configurations. Ensure compliance with RoHS directives if required for the specific application environment.
Selection Notes
Select this component when an octal buffer with separate enable controls for four outputs each is required. Compare propagation delays against system timing requirements. Evaluate power dissipation specifications relative to thermal constraints. Consider the PDIP package dimensions for PCB layout compatibility.
Part Context
This device belongs to the 81LS series of logic components. It shares functional similarities with the DM81LS95A and DM81LS96A but differs in its enable configuration. The DM81LS97A uniquely separates enable lines into two groups, unlike the common enable found in other variants within the same family.

FAQ
How are the output enable lines configured?
The DM81LS97AN has two active LOW enable inputs: G1 controls outputs Y1-Y4, and G2 controls outputs Y5-Y8.
What is the logic function of the device?
It acts as an octal buffer, passing input data to the outputs when enabled, without inversion.
