74HC245D,652

Overview

The Nexperia 74HC245D,652 is an octal bus transceiver with 3-state outputs housed in a SO20 plastic small outline package (SOT163-1). It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features non-inverting data transfer controlled by Output Enable (OE) and Direction (DIR) inputs. Inputs include clamp diodes for interfacing with voltages exceeding VCC. Static characteristics specify high-level output current up to -7.8 mA at 6.0 V and low-level output current up to 7.8 mA.

Feature Summary

• Octal bidirectional bus interface with non-inverting 3-state outputs
• Wide supply voltage range supporting mixed logic levels
• Input clamp diodes enable direct interfacing with voltages above VCC
• ESD protection exceeds 2000 V HBM and 1000 V CDM

Applications

• Memory mapping
• Clock drivers
• Bus-oriented transmissions

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm the temperature grade aligns with system requirements. Check the latest datasheet revision for any updates to electrical characteristics or pinning configurations before finalizing design specifications.

Selection Notes

Select this component for applications requiring 8-bit bidirectional data transfer. Ensure the logic family compatibility matches the source and destination devices. Verify that the operating voltage falls within the specified 2.0 V to 6.0 V range. Consider the thermal dissipation capabilities of the SO20 package for the intended power load.

Part Context

This part belongs to the 74HC/HCT series of CMOS logic devices manufactured by Nexperia. It is designed for general-purpose digital applications requiring robust signal transmission across buses. The HC series offers standard CMOS performance, while the HCT series provides TTL-compatible input thresholds.

Replacement Considerations

Direct functional equivalents include other manufacturers' 74HC245 variants in SO20 packages. Cross-reference pinouts and electrical specifications carefully when substituting. Ensure the replacement part meets the same ESD protection and latch-up performance standards.
