Комментарии об отличиях

SN74AHCT540 ↔ RS540T

SN74AHCT540 (TI) vs RS540T (Run-IC). AHCT540: supply 4.5V-5.5V, TTL inputs, output drive ±8mA, tpd typ 7.5ns. RS540T: supply 4.5V-5.5V, TTL inputs, output drive ±32mA, tpd ~4-5ns. При замене: 1) TTL input thresholds совпадают; 2) Output drive в 4 раза выше — strong driver, проверьте ground bounce при simultaneous switching; 3) tpd в 1.5-2 раза ниже — timing; 4) ICC ниже; 5) Pinout идентичный. Pin-to-pin для TTL-level bus buffer applications.
