What are the key features of SN74LVT162244AZQLR?
- 16-bit non-inverting unidirectional bus buffer with 3.3 V LVT supply for high-drive bus expansion in dense digital systems
- Active-low output enable controls in a 56-ball BGA package reducing PCB footprint compared to equivalent TSSOP-48 line drivers
- 12 mA output drive per pin with 50 pF load rating enabling direct connection to high-capacitance backplane and memory bus traces
What is SN74LVT162244AZQLR used for?
SN74LVT162244AZQLR is used in high-density processor and FPGA boards to buffer address, data, and control buses between logic devices and memory arrays or peripheral expansion connectors. Its 16-bit width and active-low enable inputs allow two independent 8-bit banks to be controlled separately, making it ideal for byte-wide memory interfaces and byte-lane bus isolation in DDR controller front ends. The 56-ball BGA package suits compact PCB layouts in networking line cards, industrial motion controllers, and server compute modules where routing density is constrained.

Frequently Asked Questions
What output drive capability does SN74LVT162244AZQLR provide per pin and which bus load scenarios does that support?
Each output of SN74LVT162244AZQLR sources or sinks 12 mA, sufficient to drive a 50 pF capacitive load at 3.3 V LVT speeds. This drive level handles typical backplane trace capacitance and the input capacitance of 8 to 16 standard LVT or LVTTL loads. For heavily loaded buses with more than 16 receivers or long PCB traces above 100 mm, a second buffer stage may be needed to maintain signal integrity within the setup/hold time budget.
How does the SN74LVT162244AZQLR 56-ball BGA package compare to the TSSOP-48 version for routing density in a server board design?
The 56-ball BGA package of SN74LVT162244AZQLR has a 6x10 mm footprint with 0.8 mm ball pitch, significantly smaller than the TSSOP-48 package that spans roughly 12.5 x 6.1 mm. BGA placement allows signal vias directly under the device, reducing stub length on 16-bit bus traces by up to 50% compared to peripheral-lead TSSOP routing. This lower stub capacitance improves signal integrity at clock rates above 100 MHz in DDR-adjacent buffer applications.
Can SN74LVT162244AZQLR operate in a mixed 5 V and 3.3 V system where bus masters drive 5 V TTL-level signals?
SN74LVT162244AZQLR inputs are 5 V tolerant, accepting logic-high signals up to 5.5 V while the device operates from a 3.3 V supply. This allows direct connection to 5 V TTL bus masters without clamping diodes or series resistors on the 16 input pins. Outputs swing between 0 V and 3.3 V, so downstream receivers must accept 3.3 V LVTTL levels, which is the case for most modern FPGA I/O banks and microcontrollers with LVT-compatible input thresholds.
Which control application can use SN74LVT162244AZQLR to separately enable two 8-bit data paths on an industrial backplane?
SN74LVT162244AZQLR has two independent active-low output enable pins, each controlling one 8-bit group of the 16-bit buffer. An FPGA or CPLD with 2 GPIO outputs can independently gate the high byte and low byte lanes, allowing selective bus isolation during byte-wide DMA transfers or arbitration in industrial programmable logic controllers. Operating the 3.3 V device at 50 pF load with a 12 mA drive, each lane maintains valid logic levels even when one byte group is tri-stated, preventing bus contention.
