What are the key features of 74ALVCH16260DGGRG4?
- 12-bit 3-state bus transceiver with multiplexed latch enables bidirectional data flow and transparent/registered latch modes in a single 56-pin TSSOP IC
- ALVCH logic family supports 1.65 V to 3.6 V operation with 5 V tolerant inputs for mixed-voltage bus bridging between 3.3 V FPGA and 5 V legacy logic
- 24 mA output drive strength sustains signal integrity on heavily loaded PCB buses with up to 32 parallel devices and trace lengths exceeding 15 cm
What is 74ALVCH16260DGGRG4 used for?
74ALVCH16260DGGRG4 is used in high-density logic systems, FPGAs, and DSPs requiring bidirectional 12-bit data bus buffering with registered latch capability. Its 3-state outputs enable shared-bus architectures in memory controllers and bus expanders where multiple bus masters contend for a common 12-bit data path. The 56-pin TSSOP package supports high pin-count logic integration on compact embedded computing and networking PCBs.

Frequently Asked Questions
How does the 3-state output of 74ALVCH16260DGGRG4 enable shared bus architectures?
The 3-state output of 74ALVCH16260DGGRG4 allows its 12 output drivers to be placed in high-impedance state when the device is not actively driving, letting other bus masters take control of the 12-bit data bus. This is essential in memory controller designs where 4 to 8 bus masters share a common 16-bit SRAM bus, preventing data contention and bus conflict errors.
Can 74ALVCH16260DGGRG4 interface 3.3 V FPGA outputs to 5 V legacy logic buses?
74ALVCH16260DGGRG4 inputs are 5 V tolerant while the device operates from a 1.65 V to 3.6 V supply, enabling direct level translation between a 3.3 V FPGA GPIO bank and a 5 V TTL legacy bus without external resistors. This interface is commonly used when migrating older 5 V microprocessor bus designs to modern 3.3 V FPGAs while retaining 5 V peripheral compatibility.
What is the output drive current of 74ALVCH16260DGGRG4 for driving loaded backplane buses?
74ALVCH16260DGGRG4 provides 24 mA output drive current per pin, sufficient to drive backplane traces with up to 32 parallel device loads and 100 pF of parasitic capacitance while maintaining valid logic levels. At 24 mA, the device can also drive 33 Ω transmission line termination resistors on high-speed 50 MHz bus designs without voltage droop below 2.4 V logic-high threshold.
How does 74ALVCH16260DGGRG4 compare to 74LVCH16260 for mixed-voltage board designs?
74ALVCH16260DGGRG4 extends the supply voltage floor to 1.65 V versus 2.7 V minimum for 74LVCH16260, allowing operation from 1.8 V FPGA core supply rails found in modern Xilinx or Intel FPGAs. Both provide 12-bit 3-state bus transceiver functionality in a 56-pin TSSOP footprint, but the ALVCH variant is preferred in low-voltage designs to avoid the need for a separate 2.5 V or 3.3 V LDO rail for the logic bus.
