STMicroelectronics 74VCX1632245 Low-Voltage Dual Supply Translating Transceiver
The 74VCX1632245 from STMicroelectronics is a versatile, high-speed dual supply translating transceiver designed to address the needs of multi-voltage systems by allowing voltage level translation between 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V buses. This makes it an ideal choice for interfacing devices that operate at different voltage levels within the same system.
Featuring 16-bit dual-directional data flow and nOE inputs for each 8-bit section, this transceiver provides the flexibility to control the direction of the data flow, making it suitable for multiplexed data transmission. The device's bus hold on data inputs eliminates the need for external pull-up or pull-down resistors, simplifying the design and reducing component count.
Constructed with advanced sub-micron silicon gate and five-layer metal wiring C2MOS technology, the 74VCX1632245 offers reduced power consumption without sacrificing speed. It is designed to operate over a broad voltage range (1.2V to 3.6V on A side and 1.65V to 5.5V on B side) and provides guaranteed data rates of up to 380 Mbps (190 MHz) while maintaining signal integrity.
The device also features power-off protection on inputs and outputs and a power-down feature that places the device in a low power state when deselected, further enhancing its suitability for battery-operated, low-power applications. Additionally, the 74VCX1632245 is equipped with LVTTL-compatible control inputs, ensuring compatibility with traditional 3.3V LVTTL logic levels.
STMicroelectronics has packaged the 74VCX1632245 in a TSSOP48 (Thin Shrink Small Outline Package) that offers space-saving advantages and is RoHS compliant, aligning with environmental standards. The product is well-suited for a wide range of applications, including telecommunication, computing, and industrial sectors, where mixed voltage environments and data bus translation are common.
With its robust design and advanced features, the 74VCX1632245 translating transceiver is a reliable and efficient solution for modern electronic systems requiring voltage level translation between different logic devices.
