SN74LVC16244ADGG

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16244A is a 16-bit buffer and driver featuring three-state outputs, designed for operation within a supply voltage range of 1.65 V to 3.6 V. It provides symmetrical active-low output-enable inputs and accepts input voltages up to 5.5 V, facilitating mixed-mode signal operations in 3.3-V and 5-V systems. The device supports live insertion via partial-power-down mode and back-drive protection. It offers a maximum propagation delay of 4.1 ns at 3.3 V and includes ESD protection exceeding 2000 V per the human-body model.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant required, as the SN74LVC16244A family includes TSSOP (DGG), TVSOP (DGV), and SSOP (DL) options. Confirm that the selected part number matches the intended operating temperature range and moisture sensitivity level. Ensure all unused inputs are tied to VCC or GND during implementation to prevent undefined operational states.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing wide-bus memory address drivers, clock drivers, or bus-oriented receivers requiring 16-bit data handling. It is suitable for applications needing down-voltage translation between 5-V and 3.3-V domains. Consider the four separate enable pins if independent control over 4-bit sections of the bus is necessary for isolation purposes.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to Texas Instruments' Widebus Family, specifically engineered to improve performance and density in digital logic circuits. It functions as four 4-bit buffers, two 8-bit buffers, or one single 16-bit buffer. The CMOS technology ensures balanced output drive capabilities while maintaining low power consumption characteristics across the specified voltage range.

Buffers, Drivers, Receivers, Transceivers FAQ

Can the SN74LVC16244A be used for voltage translation?

Yes, the device allows down voltage translation because its inputs accept voltages up to 5.5 V while operating from lower supply voltages like 3.3 V.

What is the function of the Ioff feature?

The Ioff feature allows voltages to exist on the inputs and outputs even when VCC is at 0 V, supporting partial-power-down mode and live insertion.
