SN74LVC162244DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC162244 is a 16-bit buffer and driver with 3-state outputs designed for 2.7-V to 3.6-V VCC operation. It utilizes EPIC submicron CMOS technology and features symmetrical active-low output-enable inputs. The device provides true outputs capable of sinking up to 12 mA, incorporating equivalent 26-ohm series resistors to reduce overshoot and undershoot without external components. Typical VOLP is 2 V at VCC = 3.3 V. Propagation delay ranges from 1.5 ns to 8 ns depending on voltage. It includes bus-hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific order matches the SN74LVC162244 designation rather than similar variants like SN74LVTH162244DLR or SN74LVC162244ADGVR. Confirm package type requirements against available options such as SSOP-48 (DL) or TVSOP-48 (DGG). Ensure operating conditions align with the specified 2.7-V to 3.6-V supply range and -40°C to 85°C temperature limits before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit buffering within the 2.7-V to 3.6-V voltage domain. It is suitable for applications needing high-density 3-state drivers where internal series resistance reduces EMI. Consider its bus-hold feature if external pull-up or pull-down resistors are undesirable. Verify compatibility with target clock speeds given the propagation delay specifications across the recommended voltage range.
