Frequently Asked Questions
How many channels does the SN74ABT2244APWRG4 have?
The SN74ABT2244APWRG4 contains eight buffer channels organized as two independent 4-bit groups, each with its own active-low output enable (OE) control. This configuration allows the two 4-bit sections to be independently enabled or placed in high-impedance 3-state mode, providing flexible partial bus control in 8-bit data path designs.
What logic family does the SN74ABT2244APWRG4 belong to?
The SN74ABT2244APWRG4 belongs to the ABT (Advanced BiCMOS Technology) logic family, which uses CMOS logic inputs for low input current and bipolar transistor outputs for improved drive capability compared to pure CMOS families. ABT-family devices provide fast propagation delays and are TTL-compatible, making them interoperable with both CMOS and TTL logic systems in mixed-technology designs.
What package does the SN74ABT2244APWRG4 use?
The SN74ABT2244APWRG4 is available in a 20-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm pin pitch, in tape-and-reel format indicated by the R in the part number suffix. The TSSOP-20 package provides a compact footprint suitable for high-density PCB designs and is compatible with standard automated SMT pick-and-place assembly equipment.
Is the SN74ABT2244APWRG4 inverting or non-inverting?
The SN74ABT2244APWRG4 is a non-inverting buffer, meaning the logic state at each output matches the logic state at the corresponding input when the output enable is active. This makes it suitable for transparent bus driving applications where signal polarity must be preserved without inversion, unlike inverting buffers which would require additional signal correction.
