IDT74ALVCH162245 3.3V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT BUS IDT74ALVCH162245 TRANSCIEVER WITH 3-STATE OUTPUTS AND BUS-HOLD FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology This 16-bit bus transceiver is built using advanced dual metal CMOS Typical tSK(o) (Output Skew) < 250ps technology. The ALVCH162245 is designed for asynchronous com- ESD > 2000V per MIL-STD-883, Method 3015 > 200V using munication between data buses. The control-function implementation machine model (C = 200pF, R = 0) minimizes external timing requirements. VCC = 3.3V 0.3V, Normal Range This device can be used as two 8-bit transceivers or one 16-bit VCC = 2.7V to 3.6V, Extended Range transceiver. It allows data transmission from the A bus to the B bus or VCC = 2.5V 0.2V from the B bus to the A bus, depending on the logic level at the CMOS power levels (0.4 W typ. static) direction-control (DIR) input. The output-enable (OE) input can be Rail-to-Rail output swing for increased noise margin used to disable the device so that the buses are effectively isolated. Available in TSSOP package The ALVCH162245 has series resistors in the device out-put struc- ture of the A port which will significantly reduce line noise when used DRIVE FEATURES: with light loads. This driver has been designed to drive 12mA at the Balanced Output Drivers: 12mA (A port) designated threshold levels. The B port has a 24mA driver. High Output Drivers: 24mA (B port) The ALVCH162245 has bus-hold which retains the inputs last state whenever the input bus goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors.
