Low Voltage 18-Bit Universal Bus Driver
with Bushold and 3-STATE Outputs
General Description
The LVTH16835 is an 18-bit universal bus driver that com-
bines D-type latches and D-type flip-flops to allow data flow
in transparent, latched and clocked modes.
Data flow is controlled by output-enable (OE), latch-enable
(LE), and clock (CLK) inputs. The device operates in
Transparent Mode when LE is held HIGH. The device
operates in clocked mode when LE is LOW and CLK is tog-
gled. Data transfers from the Inputs (A
a Positive Edge Transition of the Clock. When OE is LOW,
the output data is enabled. When OE is HIGH the output
port is in a high impedance state.
The LVTH16835 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
The bus driver is designed for low voltage (3.3V) V
cations, but with the capability to provide a TTL interface to
a 5V environment. The LVTH16835 is fabricated with an
advanced BiCMOS technology to achieve high speed oper-
ation similar to 5V ABT while maintaining low power dissi-
pation.
