74HC245DB,112

Overview

The Nexperia 74HC245DB,112 is an octal bus transceiver with 3-state outputs. It features output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. The device complies with JEDEC standards JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V). Latch-up performance exceeds 100 mA per JESD 78 Class II Level B. ESD protection exceeds 2000 V HBM and 1000 V CDM. It operates from -40 °C to +125 °C.

Feature Summary

• Octal bidirectional bus interface
• Non-inverting 3-state outputs
• CMOS low power dissipation
• High noise immunity

Applications

• Telecommunications infrastructure
• Industrial control systems
• Test equipment

Procurement Notes

Verify the specific ordering suffix 'DB,112' against the manufacturer's current documentation to confirm package type and availability status. Confirm that the component meets all required environmental specifications for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring an 8-bit bidirectional data path with 3-state capability. Ensure the system voltage falls within the specified range of 2.0 V to 6.0 V. Verify that the operating temperature requirements align with the -40 °C to +125 °C specification range provided in the datasheet.

Part Context
