SN74LVC1T45DCKTE4

Translators, Level Shifters Overview

The SN74LVC1T45DCKTE4 is a single-bit dual-supply bus transceiver from the Texas Instruments SN74LVC1T45 series. It operates within a supply voltage range of 1.65 V to 5.5 V on both ports and features configurable voltage-level shifting with 3-state outputs. The device utilizes an SC-70 package with six pins, supporting surface-mount installation. It functions as a non-inverting logic gate with CMOS and LVTTL input levels. The component ensures reliable data transfer across different voltage domains while maintaining low power consumption.

Translators, Level Shifters Feature Summary

• Provides bidirectional data transmission between two independent voltage domains
• Configurable voltage-level shifting allows compatibility between diverse logic families
• Includes 3-state outputs for effective bus isolation when disabled
• Offers IOFF functionality to prevent current backflow during power-down states

Translators, Level Shifters Applications

• Voltage translation between low-voltage microcontrollers and higher-voltage peripherals
• Bidirectional level shifting in mixed-signal embedded systems
• Interface bridging in portable battery-operated electronic devices
• Data line buffering in multi-voltage domain communication buses

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS standards. Confirm the SC-70 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C suits your environmental conditions. Check that the 17.7 ns propagation delay meets your system timing constraints. Validate that the 32 mA output drive capability is sufficient for your load.

Translators, Level Shifters Selection Notes

Select this component when interfacing circuits with differing supply voltages requiring bidirectional flow. Consider the SC-70 package size if board space is limited compared to larger packages. Evaluate the 1.65 V minimum supply requirement against your lowest available rail. Assess the need for 3-state outputs versus simple unidirectional shifters. Compare propagation delays against other LVC family members for speed-critical paths.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC1T45 family of single-bit dual-supply bus transceivers. It shares core electrical characteristics with variants like SN74LVC1T45DCKR but differs in packaging or reel specifications. The LVC series is designed for low-voltage applications offering high speed and low power. This specific model targets compact designs needing reliable voltage translation in small form factors.

Translators, Level Shifters Replacement Considerations

SN74LVC1T45DCKRE4 serves as a direct equivalent with identical electrical specifications and pinout. SN74LVC1T45DBVR offers similar functionality in a SOT-23-6 package, requiring layout adjustments. SN74AXC1T45DCKR provides faster performance in the same SC-70 package but operates at lower voltages.
