74LVTH16835MEAX中文资料Low Voltage 18-Bit Universal Bus Driver with Bushold and 3-STATE Outputs数据手册ONSEMI规格书

描述 Description

General Description
The LVTH16835 is an 18-bit universal bus driver that combines 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 toggled. Data transfers from the Inputs (An) to Outputs (Yn) on 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) VCC applications, 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 operation similar to 5V ABT while maintaining low power dissipation.
