74AHC245BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC245BQ,115 is an octal bus transceiver with three-state outputs housed in a DHVQFN20 package (SOT764-1). It operates on a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device includes output enable (OE) and direction control (DIR) inputs. Inputs utilize Schmitt-trigger action for high noise immunity. Latch-up performance exceeds 100 mA per JESD 78 Class II Level A. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Operating temperature ranges from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission between two buses using eight bits.
• Features overvoltage tolerant inputs allowing operation in mixed voltage environments.
• Includes Schmitt-trigger inputs to convert slowly changing signals into sharply defined outputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm RoHS compliance status through official Nexperia documentation before procurement. Ensure design specifications align with the absolute maximum ratings provided in the datasheet to prevent device damage during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an 8-bit wide bus interface is required within space-constrained designs utilizing leadless packages. The CMOS logic family offers low power dissipation suitable for battery-operated systems. Verify input compatibility with the target system voltage levels, as this variant utilizes CMOS logic switching levels rather than TTL levels.
