DESCRIPTION
The 74LVC(H)162245A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3V or 5V devices. In 3-State operation, outputs can handle 5V. These features allow the use of these devices in a mixed 3.3V/5V environment. The 74LVC(H)162245A is a 16-bit transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The 74LVC(H)162245A features two output enable (nOE) inputs for easy cascading and two send/receive (nDIR) inputs for direction control. nOE controls the outputs so that the buses are effectively isolated. The 74LVC(H)162245A is design with 30 series termination resistors in both HIGH and LOW output stages to reduce line noise. This device can be used as two 8-bit transceivers or one 16-bit transceiver. The 74LVCH162245A bus hold data inputs eliminates the need for extreme pull up resistors to hold unused inputs.

NOTES: 1. All typical values are at VCC = 3.3V and Tamb = 25°C. 2. Valid for data inputs of bus hold parts (LVCH16-A) only. 3. For data inputs only, control inputs do not have a bus hold circuit. 4. The specified sustaining current at the data input holds the input below the specified VI level. 5. The specified overdrive current at the data input forces the data input to the opposite logic input state. 6. For bus hold parts, the bus hold circuit is switched off when Vi exceeds VCC allowing 5.5V on the input terminal. 7. For I/O ports the parameter IOZ includes the input leakage current.
