GTLP8T306MTC

Overview

The GTLP8T306MTC is an 8-bit LVTTL/GTLP bus transceiver in a 24-lead TSSOP package. It provides bidirectional level translation between LVTTL logic and GTLP backplane signals. The device operates with a supply voltage (VCC) of 3.15V to 3.45V and supports an operating temperature range of -40°C to +85°C. Key electrical characteristics include A port source/sink currents of ±24mA and B port sink current up to 50mA. Propagation delays are typically 4.0ns to 5.8ns, with transition times around 2.5ns to 2.6ns.

Feature Summary

• Bidirectional interface capability between LVTTL and GTLP logic levels
• Internal output edge-rate control circuitry to minimize bus noise
• External VREF pin for adjustable receiver threshold settings
• PVT compensation circuitry ensuring consistent performance across process, voltage, and temperature variations

Applications

• High-speed backplane interfaces requiring GTLP signal levels
• System cards operating at LVTTL logic levels connecting to GTLP buses
• Data transmission systems utilizing non-inverting data polarity

Procurement Notes

Verify the specific ordering code suffix 'X' if tape and reel packaging is required, as standard units may differ. Confirm that the component meets the necessary JEDEC MO-153 package specifications for the 24-lead Thin Shrink Small Outline Package. Ensure compatibility with the recommended operating conditions regarding supply voltage and termination voltages before finalizing procurement.

Selection Notes

Select this component when designing interfaces between LVTTL-based cards and GTLP-compliant backplanes. It is suitable for applications requiring flow-through pinouts to optimize PCB layout. Consider its 5V overvoltage tolerance on LVTTL ports and bushold inputs which eliminate the need for external pull-up resistors for unused lines.

Part Context

This device belongs to the family of 8-bit bus transceivers designed for high-speed digital communication. It utilizes Fairchild's advanced CMOS technology and serves as a derivative of the Gunning Transceiver Logic (GTL) standard. The part number GTLP8T306MTC specifically denotes the MTC24 package variant.

Replacement Considerations

Check datasheets for other 8-bit LVTTL/GTLP transceivers from the same manufacturer or competitors. Verify pinout compatibility, specifically the MTC24 footprint, and ensure equivalent electrical parameters such as propagation delay and drive strength match the original design requirements.
