Übersicht
Description
Key features include direction control (DIR) and output enable (OE) pins for managing data flow, allowing for bidirectional data transfer. The device is part of the LVCH series, known for its low power consumption and high-speed operation. It also includes features like partial power-down mode to prevent backflow current when the device is powered down, and it is designed to protect against excessive current with its drive strength capabilities.
Housed in a TSSOP-24 package, the SN74LVCH8T245PW is ideal for use in digital systems requiring a reliable and efficient translation between different voltage domains.
Equivalent
1. NXP's 74LVC8T245 - An octal dual-supply translating transceiver.
2. ON Semiconductor's NLVX8T245 - A similar dual-supply translating transceiver.
3. Microchip's 74ALVC164245 - A low-voltage bidirectional transceiver with similar functionality.
Always verify voltage levels, pin compatibility, and specific features before substituting components.
Features
1. Voltage-Level Translation: Supports dual-supply operation, allowing level translation between 1.65 V to 5.5 V for VCCA and 1.65 V to 5.5 V for VCCB.
2. High-Speed Operation: Capable of handling high data rates up to 380 Mbps (push-pull) or 100 Mbps (open-drain), making it suitable for a variety of high-speed digital interfacing applications.
3. Low Power Consumption: Features low dynamic power consumption and supports partial power-down with Ioff, preventing backflow current when the device is powered down.
4. Latch-Up Performance: Meets JEDEC standard JESD 78, Class II, offering good robustness against latch-up.
5. Control and Directionality: Includes an output enable (OE) and a direction control pin (DIR) for selecting the direction of data flow.
6. Package Type: Available in TSSOP (Thin Shrink Small Outline Package), which makes it suitable for space-constrained applications.
These features make the SN74LVCH8T245PW versatile for various communication interfaces between components operating at different voltage levels.
Pinout
Key pin functions include:
- A and B Ports (A1-A8, B1-B8): 8-bit data bus ports for input/output.
- DIR (Direction Control): Determines data flow direction between buses (A to B or B to A).
- OE (Output Enable): When low, enables the output buffers, allowing data transfer; when high, places the outputs in a high-impedance state.
- VCCA and VCCB: Power supply pins for A and B ports, respectively.
- GND: Ground connection.
These features make the SN74LVCH8T245PW suitable for mixed-signal environments where voltage levels between communicating devices differ.
