Frequently Asked Questions

How much output current can each channel of the CD74ACT245M96G4 sink in a 5 V bus design?

Each output channel can sink up to 24 mA in the low state, which is sufficient to drive multiple TTL-compatible inputs and maintain valid logic levels across a 50 pF loaded data bus without external buffers.

How does direction control work on the CD74ACT245M96G4 for bidirectional data transfers?

A single DIR pin sets the data flow direction for all 8 channels simultaneously: a logic high drives data from the A-side to the B-side, while a logic low reverses the flow, allowing bus-master and slave devices to share the same 8-bit bus.

In a 3.3 V microprocessor system, can the CD74ACT245M96G4 interface to 5 V legacy peripherals?

The ACT family accepts TTL-level inputs (VIH min 2 V), so a 3.3 V microcontroller can drive the A-side inputs while the B-side outputs swing to 5 V, provided the device supply is 5 V and the microcontroller I/O is 5 V-tolerant.

When would you select the CD74ACT245M96G4 over an HC245 in a high-drive backplane design?

The ACT245 is preferred when the bus load exceeds what the HC family can handle: with 24 mA sink capability versus the HC family's 8 mA, the ACT device supports more parallel loads at 50 pF each, reducing signal degradation across long PCB traces.
