Overview
The SN74GTL16612ADGGR is an 18-bit universal bus transceiver manufactured by Texas Instruments. It facilitates voltage level translation between LVTTL and GTL/GTL+ logic families in both directions. The device operates within a supply voltage range of 3.15 V to 5.25 V. It features a propagation delay of 6.3 ns and supports surface mount installation in a TSSOP-56 package. The component functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Supports bidirectional voltage level translation between LVTTL and GTL/GTL+ standards
- Provides 18-bit universal bus transceiver functionality for mixed-voltage system integration
Applications
- Interfacing low-voltage TTL logic with GTL/GTL+ memory systems
- Voltage level conversion in high-speed data buses
- Mixed-voltage digital circuit design requiring signal integrity
Procurement Notes
Verify the specific suffix 'ADGGR' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and commercial grade specifications. Ensure compatibility with required operating temperatures and voltage levels before procurement. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status.
Selection Notes
Select this component when interfacing LVTTL sources with GTL or GTL+ loads requiring 18-bit parallel data transfer. Verify that the system power supply falls within the 3.15 V to 5.25 V operational range. Confirm that the TSSOP-56 package dimensions fit the PCB layout constraints. Ensure the application does not exceed the specified propagation delay requirements for the target bus speed.
Part Context
This device belongs to the SN74GTL16612 series, which specializes in voltage level translation. It serves as a bridge between different logic families, enabling communication between components operating at distinct voltage levels. The series is designed for applications requiring reliable data transmission across mixed-voltage domains without signal degradation.
Replacement Considerations
Consult official Texas Instruments substitution guides for verified alternatives. Generic equivalents may lack compatible electrical characteristics or pin configurations.
