3.3V CMOS
18-BIT UNIVERSAL BUS
TRANSCEIVER WITH 3 STATE OUTPUTS,
5 VOLT TOLERANT I/O
DESCRIPTION:
FEATURES:
The LVC16601A 18-bit universal bus transceiver is built using advanced
dual metal CMOS technology. This 18-bit universal 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. The clock can be controlled by the clock-enable (CLKENAB and
CLKENBA) inputs.
For A-to-B data flow, the device operates in the 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. Output enable OEAB is
active low. When OEAB is low, the outputs are active. When OEAB is high,
the outputs are in the high-impedance state. Data flow for B to A is similar
to that of A to B but uses OEBA, LEBA, CLKBA and CLKENBA.
All pins can be driven from either 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mixed 3.3V/5V supply system.
The LVC16601A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
• Typical tSK(o) (Output Skew) < 250ps
