SN74LVCH16952A 具有三态输出的 16 位寄存收发器

SN74LVCH16952A 描述

This 16-bit registered transceiver is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVCH16952A contains two sets of D-type flip-flops for temporary storage of data flowing in either direction. The 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 (CEAB\ or CEBA\) 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
