SN74LVC1T45DBVR

SN74LVC1T45DBVR is a single-bit, bidirectional, voltage-level translator manufactured by Texas Instruments (TI). This device allows for the conversion of logic levels between different voltage nodes, making it suitable for use in systems with mixed voltage levels.

Key Features:

• Bidirectional Communication:

  • SN74LVC1T45DBVR supports bidirectional communication, allowing data to be transmitted in both directions between two buses.

• Dual Power Supplies:

  • It uses two independent and configurable power supply rails, VCCA and VCCB. Both power supplies can accept voltages ranging from 1.65V to 5.5V, enabling compatibility with various voltage nodes such as 1.8V, 2.5V, 3.3V, and 5V.

• Direction Control (DIR):

  • The direction of data flow is controlled by the DIR input. When the DIR input is activated, the device either outputs data from port A to port B or from port B to port A.

• ESD Protection:

  • The device features ESD protection that exceeds the standards specified in JESD 22 –2000 for human-body model (A114-A), machine model (A115-A), and charged-device model (C101).

• VCC Isolation:

  • If either of the VCC inputs is grounded, both ports enter a high-impedance state, providing isolation and preventing potential damage.

• Low Power Consumption:

  • SN74LVC1T45DBVR is designed for low power consumption, with a maximum ICC of 4µA.

• High-Speed Performance:

  • It offers high-speed data transmission rates, with a maximum data rate of 420 Mbps for 3.3V to 5V conversions, 210 Mbps for conversions to 3.3V, 140 Mbps for conversions to 2.5V, and 75 Mbps for conversions to 1.8V.

• Small Footprint:

  • The device is packaged in a compact SOT-23-6 package, making it easy to integrate into various circuit board sizes.

• Applications:

  • SN74LVC1T45DBVR is suitable for a wide range of applications, particularly those requiring different logic level conversions in low-voltage and low-power systems, such as mobile devices, embedded systems, and communication equipment.

Summary:

SN74LVC1T45DBVR is a versatile and reliable single-bit bidirectional voltage-level translator that offers high-speed performance, low power consumption, and compatibility with a wide range of voltage nodes. Its compact package and robust ESD protection make it an ideal choice for use in various electronic systems.
