Комментарии об отличиях

SN74AHCT125 ↔ RS4GT125

SN74AHCT125 (TI) vs RS4GT125 (Run-IC). AHCT125: supply 4.5V-5.5V, TTL inputs, output drive ±8mA, tpd typ 7.5ns, OE active-low (L=enabled). RS4GT125: supply 1.65V-5.5V, TTL inputs, output drive ±32mA, tpd ~5-7ns, OE active-low, IOFF support. При замене: 1) VCC range расширен до 1.65V — работает при 3.3V, 2.5V; 2) Output drive в 4 раза выше — проверьте ground bounce; 3) tpd совпадает; 4) IOFF partial power-down — новая функция; 5) OE polarity active-low — совпадает. Pin-to-pin для bus buffer с active-low OE. Проверьте pull-up на OE для power-up hi-Z state.
