GTL2005PW/DG,118

Translators, Level Shifters Overview

The GTL2005PW/DG,118 is a quad translating transceiver designed for interfacing 3.3 V systems with GTL/GTL+ buses. It operates as either a GTL-to-TTL sampling receiver or a TTL-to-GTL driver, controlled by the DIR pin. The LVTTL interface supports voltages up to 5.5 V. Supply voltage ranges from 3.0 V to 3.6 V. Input capacitance is 2.3 pF to 3.5 pF for control inputs and 3.4 pF to 7.0 pF for I/O ports. Propagation delays range from 1.9 ns to 5.9 ns depending on direction and GTL variant.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package and tape/reel configuration. Confirm the component status as active or obsolete through official NXP channels before finalizing procurement plans. Ensure environmental compliance requirements align with project specifications.

Translators, Level Shifters Selection Notes

Select this component when bridging 3.3 V logic with GTL/GTL+ buses is required. The 5.5 V tolerance on B port inputs allows compatibility with 5 V systems. Consider the DIR pin functionality for unidirectional data flow control in complex multi-voltage architectures.

Translators, Level Shifters Part Context

The GTL2005 belongs to the family of translating transceivers designed for Gunning Transceiver Logic (GTL) interfaces. It provides a solution for connecting different voltage domains within electronic systems, specifically focusing on the transition between low voltage transistor-transistor logic and GTL standards.

Translators, Level Shifters FAQ

How is the data direction controlled?

Direction is controlled by the DIR pin. A HIGH level configures the device as a GTL-to-TTL sampling receiver, while a LOW level sets it as a TTL-to-GTL driver.

What is the maximum input voltage for the B port?

The B port (TTL side) is tolerant up to 5.5 V, allowing direct connection to 5 V CMOS or TTL outputs.
