Overview
The MC74AC245DWR2G is an octal bidirectional transceiver with 3-state inputs and outputs, manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40°C to +85°C. The device features non-inverting buffers with a propagation delay of up to 9.0 ns at 5.0 V. It provides a current sinking capability of 24 mA at both the A and B ports. The component is housed in a SOIC-20W package (Case 751D) and is supplied in tape and reel packaging.
Feature Summary
- Bidirectional data path controlled by Transmit/Receive input
- High current output sourcing and sinking capability
- Three-state outputs for bus-oriented applications
Applications
- Bus-oriented systems requiring bidirectional data transfer
- Memory and memory interface control
- Clock drivers and buffered oscillators
Procurement Notes
Verify the specific ordering suffix 'DWR2G' corresponds to the SOIC-20 Wide package and tape and reel shipping configuration. Confirm that the Pb-Free designation aligns with project environmental compliance requirements. Ensure the operating voltage and temperature ranges meet the target application specifications before finalizing procurement.
Selection Notes
Select this component when an octal bidirectional buffer with high drive capability is required. The AC logic family offers faster switching speeds compared to HC series devices. Verify that the 3-state outputs are compatible with the system bus architecture. Consider the SOIC-20W package dimensions for PCB layout constraints.
Part Context
This part belongs to the MC74AC245/74ACT245 family of octal bidirectional transceivers. The AC variant utilizes CMOS technology for low power consumption and high noise immunity. It serves as a standard interface solution for connecting microprocessors, memory devices, and other digital logic components in parallel bus architectures.
Replacement Considerations
MC74AC245DTG: TSSOP-20 package variant. MC74AC245DWG: SOIC-20 tube packaging variant.
