1. 74FCT162245ATPAG Substitution Conclusion
The 74FCT162245ATPAG is a fully compatible electrical and functional replacement for the original 74FCT162H245ATPVC device. Key parameters such as logic type (non-inverting transceiver), number of elements (2), bits per element (8‑bit), output type (3‑state), output current (24 mA high/low), and supply voltage range (4.5 V to 5.5 V) are identical. The primary difference lies in the package: the original 48‑BSSOP (7.50 mm wide) is replaced by a 48‑TFSOP (6.10 mm wide), resulting in a smaller footprint and reduced board space. Pin‑out and electrical connections remain essentially compatible; however, the PCB layout must be redesigned to accommodate the narrower package width. Additionally, note the manufacturer change from Texas Instruments to Renesas, which may introduce supply‑chain and documentation variations. Performance is expected to remain consistent.
2. 74FCT162245CTPAG8 Substitution Conclusion
The 74FCT162245CTPAG8 is electrically equivalent to the original 74FCT162H245ATPVC in core parameters, including logic function, current‑drive capability, and operating voltage range, making it a functionally viable substitute. The package is similarly changed to a 48‑TFSOP (6.10 mm wide), requiring corresponding PCB layout adjustments as with the 74FCT162245ATPAG. The suffix “C” in the part number may indicate a minor revision or commercial‑grade temperature rating; however, no explicit temperature‑range difference is indicated in the given parameters. It is assumed compatible, but the datasheet should be verified to confirm there are no hidden performance deviations—such as propagation delay or power consumption—that could affect application‑specific margins. Overall, the differences do not impact basic functionality.
