74LVTH16835
Low Voltage 18-Bit Universal Bus Driver
with 3-STATE Outputs (Preliminary)
General Description
The LVTH16835 consists of 18-bit universal bus drivers
which combine D-type latches and D-type flip-flops to allow
data flow in transparent, latched, or clocked modes. Data
flow from A to Y is controlled by the output-enable (OE)
input. This device operates in the transparent mode when
the latch-enable (LE) input is HIGH. The A data is latched if
the clock (CLK) input is held at a HIGH or LOW logic level.
If LE is LOW, the A-bus data is stored in the latch/flip-flop
on the LOW-to-HIGH transition of the CLK. When OE is
HIGH, the outputs are in the 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.
