The ALVCH16952 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.
The ALVCH16952 has been designed with a ±24mA output driver.
This driver is capable of driving a moderate to heavy load while maintaining speed performance.
The ALVCH16952 has “bus-hold” which retains the inputs’ last state whenever the input bus goes to a high impedance.
This prevents floating inputs and eliminates the need for pull-up/down resistors.
