The 74LCX543MSAX is a low voltage octal registered transceiver designed for data flow in both directions, featuring two sets of D-type registers for temporary data storage. It operates at supply voltages of 2.3V to 3.6V and is capable of interfacing with 5V signal environments, making it suitable for low voltage applications. The device supports a maximum propagation delay of 7.0 ns at 3.3V and has a maximum supply current of 10 µA, ensuring low power dissipation. This transceiver includes separate latch enable and output enable inputs for independent control of data flow, and it can drive outputs with up to ±24 mA at 3.0V. The 74LCX543MSAX also features power-down high impedance states, supports live insertion and withdrawal, and incorporates patented noise and EMI reduction circuitry. Its robust ESD performance exceeds 2000V for the human body model, ensuring reliability in various applications. The device is available in multiple package types, including the 24-Lead Shrink Small Outline Package (SSOP).
