FEATURES:
DESCRIPTION:
DRIVE FEATURES:
* High Output Drivers: 24mA * Suitable for heavy loads
This 16-bit registered transceiver is built using advanced dual metal CMOS technology. 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.
APPLICATIONS:
* 3.3V high speed systems * 3.3V and lower voltage computing systems
