Texas Instruments SN74ALVCH162373 16-Bit Transparent D-Type Latch with 3-State Outputs SN74ALVCH162373LR

The SN74ALVCH162373LR is a 16-bit transparent D-type latch designed for operation within a supply voltage range of 1.65 V to 3.6 V. It features three-state outputs, allowing for flexible interfacing in digital circuits. This device can function as two 8-bit latches or one 16-bit latch, making it versatile for various applications such as buffer registers, I/O ports, and bidirectional bus drivers. The latch enables data to be latched when the latch-enable (LE) input is low, while the output-enable (OE) input allows the outputs to be placed in a high-impedance state, facilitating bus line driving without additional components. The device includes bus-hold circuitry to maintain valid logic levels on unused inputs, eliminating the need for external pull-up or pull-down resistors. It is also designed to withstand latch-up conditions exceeding 250 mA and provides ESD protection of up to 2000 V per the Human Body Model. The SN74ALVCH162373LR is available in multiple package options, including the 48-pin SSOP and TSSOP, suitable for various PCB layouts. Its output ports can sink up to 12 mA and are equipped with equivalent series resistors to minimize overshoot and undershoot, enhancing reliability in high-speed applications.
