Texas Instruments CY74FCT2543T Octal Registered Transceivers with 3-State Outputs and Series Damping Resistors 74FCT2543ATSOCTE4

The CY74FCT2543T is an octal registered transceiver featuring 3-state outputs and series damping resistors, designed for efficient data flow control between two sets of eight D-type latches. It supports independent data direction control with separate latch enable and output enable inputs for both A-to-B and B-to-A data transfers. The device is compatible with TTL logic levels and offers a typical output high voltage of 3.3 V, with a maximum output sink current of 12 mA and source current of 15 mA. This transceiver includes on-chip series resistors to minimize transmission-line reflection noise, enhancing signal integrity. It is specified for partial-power-down applications, utilizing Ioff circuitry to prevent backflow current when powered down. The device also features edge-rate control circuitry for improved noise characteristics and is designed to withstand ESD protection levels exceeding industry standards. The operating temperature range is from -40°C to 85°C, making it suitable for various applications.
