具有三态输出的 12 位至 24 位多路复用 D 类锁存器 56-TSSOP -40 to 85
This 12-bit to 24-bit multiplexed D-type latch is designed for 1.65-V to 3.6-VCC operation.
The SN74ALVCH162260 is used in applications in which two separate data paths must be multiplexed onto, or demultiplexed from, a single data path. Typical applications include multiplexing and/or demultiplexing address and data information in microprocessor or bus-interface applications. This device also is useful in memory-interleaving applications.
Three 12-bit I/O ports A1-A12, 1B1-1B12, and 2B1-2B12 are available for address and/or data transfer. The output-enable OE1B\, OE2B\, and OEA\\\\ inputs control the bus transceiver functions. The OE1B\ and OE2B\ control signals also allow bank control in the A-to-B direction.
Address and/or data information can be stored using the internal storage latches. The latch-enable LE1B, LE2B, LEA1B, and LEA2B inputs are used to control data storage. When the latch-enable input is high, the latch is transparent. When the latch-enable input goes low, the data present at the inputs is latched and remains latched until the latch-enable input is returned high.
The B outputs, which are designed to sink up to 12 mA, include equivalent 26- resistors to reduce overshoot and undershoot.
To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH162260 is characterized for operation from 40°C to 85°C.
