DESCRIPTION:

CMOS technology. This high-speed, low power 18-bit registered bus

transceiver combines D-type latches and D-type flip-flops to allow data flow

in transparent latched and clocked modes. Data flow in each direction is

controlled by output-enable (OEAB and OEBA), latch enable (LEAB and

LEBA) and clock (CLKAB and CLKBA) inputs. For A-to-B data flow, the

device operates in transparent mode when LEAB is high. When LEAB is

low, the A data is latched if CLKAB is held at a high or low logic level. If LEAB

is low, the A bus data is stored in the latch/flip-flop on the low-to-high transition

of CLKAB. OEAB performs the output enable function on the B port. Data

flow from B port to A port is similar but requires using OEBA, LEBA and

CLKBA. Flow-through organization of signal pins simplifies layout. All inputs

are designed with hysteresis for improved noise margin.

driver is capable of driving a moderate to heavy load while maintaining

speed performance.

whenever the input goes to a high impedance. This prevents floating inputs

and eliminates the need for pull-up/down resistors.

This 18-bit registered transceiver is built using advanced dual metal

The LVCH16501A has been designed with a ±24mA output driver. This

The LVCH16501A has “bus-hold” which retains the inputs’ last state
