SN74GTLP1395DWE4

The SN74GTLP1395DWE4 is one member of the SN74GTLP1395 series.The SN74GTLP1395 is two 1-bit, high-drive, 3-wire bus transceivers that provide LVTTL-to-GTLP and GTLP-to-LVTTL signal-level translation for applications, such as primary and secondary clocks, that require individual output-enable and true/complement controls. The device allows for transparent and inverted transparent modes of data transfer with separate LVTTL input and LVTTL output pins, which provide a feedback path for control and diagnostics monitoring.

Features of the SN74GTLP1395DWE4 are:(1)TI-OPC circuitry limits ringing on unevenly loaded backplanes; (2)OEC circuitry improves signal integrity and reduces electromagnetic interference; (3)bidirectional interface between GTLP Signal levels and LVTTL logic levels; (4)split LVTTL port provides a feedback path for control and diagnostics monitoring; (5)LVTTL interfaces Are 5-V tolerant; (6)high-drive GTLP Outputs (100 mA); (7)LVTTL outputs (24 mA/24 mA); (8)variable edge-rate control (ERC) input selects GTLP rise and fall times for optimal data-transfer rate and signal integrity in distributed loads; (9)Ioff, power-up 3-State, and BIAS VCC support live insertion; (10)polarity control selects true or complementary outputs; (11)latch-up performance exceeds 100 mA Per JESD 78, class II.

The absolute maximum ratings of the SN74GTLP1395DWE4 can be summarized as:(1)supply voltage range:-0.5 to 4.6V;(2)input voltage range:-0.5 to 7.0V;(3)current into any output in the low state:48 mA;(4)input clamp current:-50mA;(5)voltage range applied to any output in the high-impedance or power-off state:0.5 V to 7 V; (6)storage temperature range:-65 to 150.This GTLP device features TI-OPC circuitry, which actively limits the overshoot caused by improperly terminated backplanes, unevenly distributed cards, or empty slots during low-to-high signal transitions. This improves signal integrity, which allows adequate noise margin to be maintained at higher frequencies.High-drive GTLP backplane interface devices feature adjustable edge-rate control (ERC). Changing the ERC input voltage between low and high adjusts the B-port output rise and fall times. This allows the designer to optimize system data-transfer rate and signal integrity to the backplane load.
