描述 Description

This 16-bit registered transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVCH16952 contains two sets of D-type flip-flops for temporary storage of data flowing in either direction. This device can be used as two 8-bit transceivers or one 16-bit transceiver. Data on the A or B bus is stored in the registers on the low-to-high transition of the clock (CLKAB or CLKBA) input provided that the clock-enable (CLKENAB\\ or CLKENBA\\) input is low. Taking the output-enable (OEAB\\ or OEBA\\) input low accesses the data on either port.
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 SN74ALVCH16952 is characterized for operation from -40°C to 85°C.
