Low-Voltage 16-Bit Bus Transceiver with Bushold
The TC74VCXHR162245FT is a high-performance CMOS
16-bit bus transceiver. Designed for use in 1.8-V, 2.5-V or 3.3-V
systems, it achieves high-speed operation while maintaining the
CMOS low power dissipation.
This 16-bit bus transceiver is controlled by direction control
(DIR) inputs and output enable (OE) inputs which are common to
each byte. It can be used as two 8-bit transceivers or one 16-bit
transceiver. The direction of data transmission is determined by
the level of the DIR inputs. The OE inputs can be used to disable
the device so that the busses are effectively isolated.
The 26-鈩?series resistor helps reducing output overshoot and
undershoot without external resistor.
Weight: 0.25 g (typ.)
The A, B data inputs include active bushold circuitry,
eliminating the need for external pull-up resisisors to hold unused or floating data inputs at a valid logic level.
All inputs are equipped with protection circuits against static discharge.
