Nexperia USA Inc. 74LVC1T45GW-Q100H

The 74LVC1T45GW-Q100H, produced by Nexperia USA Inc., is a single-bit, dual-supply transceiver with 3-state outputs designed for bidirectional level translation. This device is part of the 74LVC1T45 and 74LVCH1T45 series, which are highly versatile for translating between different voltage levels commonly used in modern electronic systems.

The transceiver features two 1-bit input-output ports (A and B), a direction control input (DIR), and dual supply pins (V_CC(A) and V_CC(B)), allowing it to operate with supply voltages ranging from 1.2 V to 5.5 V. This makes it suitable for translating between various low-voltage nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V.

• Bidirectional Level Translation: Enables translation between different voltage levels (1.2 V to 5.5 V) on both input-output ports.
• Dual Supply Pins: V_CC(A) and V_CC(B) can be supplied at any voltage between 1.2 V and 5.5 V.
• Direction Control: The direction control input (DIR) allows transmission from A to B or from B to A.
• 3-State Outputs: Outputs can be set to high-impedance state.
• High Noise Immunity: Ensures reliable operation in noisy environments.
• Maximum Data Rates: Supports data rates up to 420 Mbps (3.3 V to 5.0 V translation), 210 Mbps (translation to 3.3 V), 140 Mbps (translation to 2.5 V), 75 Mbps (translation to 1.8 V), and 60 Mbps (translation to 1.5 V).
• Suspend Mode: Both A and B ports are in the high-impedance OFF-state when either V_CC(A) or V_CC(B) is at GND level.
• I_OFF Circuitry: Provides partial power-down mode operation, preventing backflow current when the device is powered down.
• Active Bus Hold Circuitry: Available in the 74LVCH1T45, holds unused or floating data inputs at a valid logic level.
• Compliance with JEDEC Standards: Meets JESD8-7, JESD8-5, JESD8C, and JESD36 standards.

• Mixed Voltage Systems: Ideal for systems that require communication between different voltage domains.
• Interface Translation: Suitable for translating signals between different logic levels in various interfaces such as USB, I2C, SPI, and more.
• Power Management Systems: Useful in power management circuits where voltage levels need to be translated efficiently.
• Consumer Electronics: Can be used in a wide range of consumer electronics that require level translation, such as smartphones, tablets, and laptops.
• Industrial Automation: Applicable in industrial automation systems where different voltage levels are used for various components.
