1. 74ABT162245ADGG:11 Substitution Conclusion The 74ABT162245ADGG:11 is fully compatible with the SN74ABT162245DGGR in terms of logic function, supply voltage, and package, making it a viable drop-in replacement. However, attention should be paid to differences in output current specifications. The original device specifies an output current of 12 mA (high) and 12 mA (low), with additional ratings of 32 mA (high) and 64 mA (low), possibly indicating drive capability under different test conditions. In contrast, the substitute device is rated for 32 mA (high) and 12 mA (low). The substitute offers higher high‑level drive current (32 mA vs. 12 mA), which may enhance performance when driving high‑level loads, while the low‑level drive current remains the same. In practice, this difference is generally acceptable. Nevertheless, it is recommended to verify compatibility based on the specific load requirements of the system, ensuring that the substitution does not introduce signal‑integrity or power‑consumption issues in high‑speed or high‑current applications.
