IDT74LVCHR162245A
IDT74LVCHR162245A is 3.3V CMOS 16-BIT BUS TRANSCEIVER manufactured by Integrated Device Technology.
TION: DRIVE Features : APPLICATIONS: - Balanced Output Drivers: ±12m A - Low switching noise - 5V and 3.3V mixed voltage systems - Data munication and telemunication systems This 16-bit bus transceiver is built using advanced dual metal CMOS technology. This high-speed, low power device is ideal for asynchronous munication between two buses (A and B). The Direction and Output Enable controls are designed to operate this device as either two independent 8-bit transceivers or one 16-bit transceiver. The direction control pin (DIR) controls the direction of data flow. The output enable pin (OE) overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin. All pins can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V supply system. The LVCHR162245A has series resistors in the device output structure which will significantly reduce line noise when used with light loads. The driver has been designed to drive ±12m A at the designated threshold levels. The LVCHR162245A has “bus-hold” which retains the inputs' last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors.
