NXP Semiconductors 74LVC1T45GM,132

The 74LVC1T45GM,132 is a dual supply translating transceiver with 3-state outputs, manufactured by NXP Semiconductors (now part of Nexperia). This device is designed for bidirectional level translation and is part of the Logic IC Chips category. It features two 1-bit input-output ports (A and B), a direction control input (DIR), and dual supply pins (VCC(A) and VCC(B)) that can operate within a wide voltage range of 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.

• Wide Supply Voltage Range: VCC(A) and VCC(B) can be supplied at any voltage between 1.2 V and 5.5 V, making it suitable for translating between various low voltage nodes.
• High Noise Immunity: Complies with JEDEC standards for noise immunity.
• ESD Protection: HBM JESD22-A114F Class 3A exceeds 4000 V and CDM JESD22-C101E exceeds 1000 V.
• Maximum Data Rates: Up to 420 Mbps for 3.3 V to 5.0 V translation, and varying rates for other voltage translations.
• Suspend Mode and IOFF Circuitry: Devices are fully specified for partial power-down applications, preventing damaging backflow current when powered down.
• Active Bus Hold Circuitry: In the 74LVCH1T45, this feature holds unused or floating data inputs at a valid logic level.
• Low Power Consumption: Maximum ICC of 16 μA).
• Multiple Package Options: Available in various packages, including XSON6 (SOT886)).
