74ALVCH16245

74ALVCH16245 Low−Voltage 16−Bit Transceiver with Bus Hold 1.8/2.5/3.3 V (3−State, Non−Inverting) The 74ALVCH16245 is an advanced performance, non−inverting 16−bit transceiver. It is designed for very high−speed, very low−power operation in 1.8 V, 2.5 V or 3.3 V systems. The 74ALVCH16245 is designed with byte control. It can be operated as two separate octals, or with the controls tied together, as a 16−bit wide function. The Transmit/Receive (T/Rn) inputs determine the direction of data flow through the bi−directional transceiver. Transmit (active−HIGH) enables data from A ports to B ports; Receive (active−LOW) enables data from B to A ports. The Output Enable inputs (OEn), when HIGH, disable both A and B ports by placing them in a HIGH Z condition. The data inputs include active bushold circuitry, eliminating the need for external pull−up resistors to hold unused or floating inputs at a valid logic state. Designed for Low Voltage Operation: VCC = 1.65 − 3.6 V 3.6 V Tolerant Inputs and Outputs High Speed Operation: 3.0 ns max for 3.0 to 3.6 V 3.7 ns max for 2.3 to 2.7 V 6.0 ns max for 1.65 to 1.95 V Static Drive: ±24 mA Drive at 3.0 V ±12 mA Drive at 2.3 V ±4 mA Drive at 1.65 V Supports Live Insertion and Withdrawal Includes Active Bushold to Hold Unused or Floating Inputs at a Valid Logic State IOFF Specification Guarantees High Impedance When VCC = 0 V† Near Zero Static Supply Current in All Three Logic States (40 mA) Substantially Reduces System Power Requ...
