Frequently Asked Questions
How many data bits does 74LVCR162245DGGRG4 handle, and what is its maximum supply voltage?
74LVCR162245DGGRG4 handles 16 bits of bidirectional data simultaneously and operates from a supply voltage up to 3.6 V, making it compatible with 3.3 V LVTTL and LVCMOS logic levels used in ARM SoCs, FPGAs, and DDR memory controller interfaces where bus widths of 16 bits or 32 bits are common.
What output current does each pin of 74LVCR162245DGGRG4 source or sink, and does it affect PCB trace impedance matching?
Each output pin of 74LVCR162245DGGRG4 can sink up to 12 mA low-side output current, which is adequate for driving standard LVCMOS loads at 3.3 V. For controlled-impedance PCB traces above 10 cm, series termination resistors of 22 Ω to 33 Ω should be added to reduce reflections on the 50 Ω–100 Ω transmission-line segments.
In an FPGA expansion board design, how does the direction control of 74LVCR162245DGGRG4 work?
74LVCR162245DGGRG4 uses a common direction control (DIR) pin shared across all 16 bits, which switches the entire bus between A-to-B and B-to-A propagation directions simultaneously. A logic-high DIR drives data from the A port to the B port, while logic-low reverses the flow, allowing an FPGA GPIO pin to control read/write bus direction with a single signal.
When would a designer choose 74LVCR162245DGGRG4 over a 74HC245 for a 3.3 V bus application?
74LVCR162245DGGRG4 is preferred over 74HC245 in 3.3 V systems because LVC logic family parts are specified for 3.3 V operation with lower propagation delay (typically under 5 ns vs. 10+ ns for HC at 3.3 V) and can interface with 5 V tolerant inputs without overvoltage damage. It also provides 16-bit width in a single package, whereas 74HC245 is only 8-bit, halving the required IC count.
