IDT74LVC4245APYG

Translators, Level Shifters Overview

The IDT74LVC4245APYG is an octal bus transceiver and voltage level shifter manufactured using 0.5 micron CMOS technology. It features dual supply rails: VCCA operates at 5V ± 0.5V, while VCCB operates between 2.7V and 3.6V. The device provides noninverting data transfer with 3-state outputs and ±24mA drive capability. All I/O pins are 5V tolerant. It supports hot insertion and includes input hysteresis for improved noise margins. The component is housed in a 24-pin SOIC package and operates within an industrial temperature range of -40°C to +85°C.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'PYG' corresponds to the Green QSOP package variant as defined in the ordering information table. Confirm that the required operating temperature range matches the industrial specification (-40°C to +85°C). Ensure the design accommodates the dual power supply requirements for VCCA and VCCB. Check for any specific handling precautions related to the CMOS technology used.

Translators, Level Shifters Selection Notes

Select this component when asynchronous communication between buses operating at different voltage levels is required. The high drive current makes it suitable for moderate to heavy loads. The 5V tolerant I/O simplifies interfacing in mixed-voltage designs. Consider the package size and pin count relative to available board space. Verify that the propagation delay characteristics meet the timing requirements of the target application.

Translators, Level Shifters Part Context

This device belongs to the LVC series of low-voltage CMOS logic components. It functions as an octal bus transceiver, allowing bidirectional data flow controlled by a direction pin. The inclusion of an output enable pin allows for tri-stating both ports independently of the direction control. This family is designed for applications requiring reliable signal translation and robust performance in mixed-voltage digital systems.

Translators, Level Shifters Replacement Considerations

Compatible substitutes include the SN74LVC4245A from Texas Instruments and the IDT74LVC4245AQG8 from Renesas. These parts share similar electrical characteristics and functionality. Verify pin compatibility and package dimensions before substitution. Ensure the replacement part meets the same voltage and temperature specifications.
