What are the key features of 74LVCH162244AGR?
- 16-channel 3-state buffer/line driver with 32 mA output drive
- 1.65 V to 3.6 V supply range with 5 V overvoltage-tolerant inputs
- Bus-hold circuitry eliminates pull-up and pull-down resistors
- Low propagation delay of approximately 2.5 ns at 3.3 V
- 48-pin TSSOP package for compact 16-bit bus interfacing
- Two independent 8-bit output-enable controls
What is 74LVCH162244AGR used for?
The 74LVCH162244AGR is widely used to buffer 16-bit data and address buses between microprocessors and memory or peripheral devices in embedded systems running at 1.8 V or 3.3 V. Its 5 V-tolerant inputs allow direct connection to legacy TTL or 5 V CMOS signals without level-shift ICs. Backplane and card-edge interfaces in industrial and communications equipment also benefit from its high drive current and bus-hold features.

Frequently Asked Questions
What is the maximum output drive current of the 74LVCH162244AGR, and why does it matter for bus applications?
Each output of the 74LVCH162244AGR can source or sink up to 32 mA, enabling it to drive heavily loaded 16-bit data buses with multiple SDRAM or Flash devices attached. At 3.3 V supply, propagation delay is approximately 2.5 ns, keeping bus timing margins comfortable even at 100 MHz system frequencies.
Can the 74LVCH162244AGR interface directly to 5 V logic without additional level translation?
Yes, its inputs are 5 V overvoltage-tolerant while the device operates from a 1.65 V to 3.6 V supply, so 5 V CMOS or TTL signals can drive the inputs directly. This removes the need for separate level-shift ICs when connecting legacy 5 V peripherals to a 3.3 V processor bus, saving board space and component count.
How does the bus-hold feature of the 74LVCH162244AGR simplify PCB design?
Bus-hold circuitry maintains the last valid logic state on each input pin when the driving source is disconnected or tri-stated, eliminating the need for 16 individual pull-up or pull-down resistors on the bus. This reduces the passive component count on the PCB and prevents floating inputs from causing spurious toggling that adds to EMI in high-speed 16-bit bus designs.
