DESCRIPTION
The 74LVC(H)16245A 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)16245A is a 16-bit transceiver featuring non-inverting
3-State bus compatible outputs in both send and receive directions.
The 74LVC(H)16245A 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. This device can be used as two 8-bit transceivers or one
16-bit transceiver.
The 74LVCH16245A bus hold data inputs eliminates the need for
extreme pull up resistors to hold unused inputs.

NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + S (CL × VCC2 × fo) where:
fi = input frequency in MHz; CL = output load capacity in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
S (CL × VCC2 × fo) = sum of the outputs.
