DESCRIPTION:

The LVCHR16501A 18-bit registered transceiver is built using advanced

dual metal 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.

The LVCHR16501A has series resistors in the device output structure

which will significantly reduce line noise when used with light loads. This

driver has been developed to drive

12mA at the designated thresholds.

The LVCHR16501A has “bus-hold” which retains the inputs’ last state

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

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

Drive Features for LVCHR16501A:

– Balanced Output Drivers: ±12mA

– Low switching noise

APPLICATIONS:

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems
