Low Voltage Bidirectional Transceiver with Bushold
74LCXH245 Low Voltage Bidirectional Transceiver with Bushold October 2000 Revised September 2001 74LCXH245 Low Voltage Bidirectional Transceiver with Bushold General Description Features The LCXH245 contains eight non-inverting bidirectional5V tolerant control inputs buffers with 3-STATE outputs and is intended for bus ori-2.3V–3.6V V specifications provided CC ented applications. The device is designed for low voltage 7.0 ns t max (V = 3.3V), 10 μA I max PD CC CC (2.5V and 3.3V) V applications. The T/R input deter- CC Power down high impedance outputs mines the direction of data flow through the device. The OE input disables both the A and B ports by placing them in a±24 mA output drive (V = 3.0V) CC high impedance state. Implements patented noise/EMI reduction circuitry The LCXH245 is fabricated with an advanced CMOS tech- Latch-up performance exceeds 500 mA nology to achieve high speed operation while maintaining Bushold on inputs eliminates the need for external CMOS low power dissipation. The LCXH16244 data inputs pull-up/pull-down resistors include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating dataESD performance: inputs at a valid logic level.
