The 20-pin DIP body is 7.62 mm wide, so it occupies the same board real estate as a 74LS245 or 74HCT245, making it a drop-in swap for existing through-hole bus transceiver positions. Supply voltage spans 2V to 6V, covering both 5V TTL legacy rails and 3.3V CMOS logic without a separate level translator. The wide margin means the part tolerates a poorly regulated 5V rail that droops to 4.5V or spikes to 5.5V — common on prototype boards and repair benches. ## 8-bit bidirectional bus control This is an 8-bit non-inverting transceiver with 3-state outputs — data flows in either direction under direction-pin control (DIR), and the output-enable pin (OE) can isolate the bus entirely. That makes it the right part for a shared data bus where multiple peripherals talk to a microcontroller: one TC74HC245APF buffers the bus, and the 3-state outputs prevent contention when the MCU is not driving. Output drive is 7.8 mA source and sink at the rated supply voltage — enough to drive up to 10 standard LSTTL loads or 5 CMOS loads per output. If your bus needs to drive LEDs, relays, or long cables, plan on adding a buffer stage; the 7.8 mA limit is the fan-out ceiling, not a load-driver. ## Industrial temperature and compliance The 74HC family logic thresholds are CMOS-compatible, so the part works with 3.3V microcontrollers without level-shifting at the input pins.","metaTitle":"Toshiba TC74HC245APF 74HC Transceiver, 20-DIP, 2-6V","metaDescription":"Toshiba TC74HC245APF 8-bit non-inverting transceiver, 3-state outputs, 2V-6V supply, 20-DIP package.

However, TC74ACT244PF is a 4-bit dual buffer (non-inverting) with 24 mA output drive and 4.5V supply, while TC74HC245APF is an 8-bit transceiver with 7.8 mA drive and 2-6V supply. The logic function differs — a transceiver vs a buffer — so verify the direction control and output-enable wiring before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TC74HC245APF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TC74HC245APF when reusing this data.
