74HC245BQ,115

Overview

The Nexperia 74HC245BQ,115 is an octal bus transceiver with 3-state outputs housed in a DHVQFN20 package (SOT764-1). It operates on a supply voltage range of 2.0 V to 6.0 V and supports CMOS input levels. The device features non-inverting data transmission controlled by Output Enable (OE) and Direction (DIR) inputs. It complies with JEDEC standards JESD8C and JESD7A, offering high noise immunity and low power dissipation.

Feature Summary

• Octal bidirectional bus interface with non-inverting 3-state outputs
• Wide supply voltage range from 2.0 V to 6.0 V
• High noise immunity and CMOS low power dissipation
• Input clamp diodes for interfacing voltages exceeding VCC

Applications

• Telecommunications infrastructure
• Industrial control systems
• Test equipment

Procurement Notes

Verify the specific ordering suffix ',115' corresponds to the DHVQFN20 package variant SOT764-1. Confirm that the CMOS logic family matches the system requirements, as the HCT variant provides TTL input levels instead. Ensure the application environment stays within the specified -40 °C to +125 °C temperature range for full operational validity.

Selection Notes

Select this component when an 8-bit bidirectional interface is required in a leadless thermal enhanced package. The HC family is suitable for general-purpose applications requiring CMOS input compatibility across a wide voltage spectrum. Consider the DHVQFN20 form factor for PCB space optimization compared to standard SO or TSSOP packages.

Part Context

This part belongs to the 74HC/HCT245 series of octal bus transceivers manufactured by Nexperia. The 'BQ' designation specifically identifies the DHVQFN20 package type, distinguishing it from other variants like the SO20 or TSSOP20. It is designed for robust signal transmission in mixed-voltage environments.

Replacement Considerations

Direct pin-compatible replacements include other 74HC245 variants in different packages such as 74HC245D or 74HC245PW, provided the package footprint allows. Cross-family substitutes like 74HCT245BQ,115 offer identical functionality but with TTL input thresholds.
