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 3.3 or 5 V devices. In
3-state operation, outputs can handle 5 V. These features
allow the use of these devices as translators in a mixed
3.3 and 5 V 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. This device can be
used as two 8-bit transceivers or one 16-bit transceiver.
The 74LVCH162245A bushold data inputs eliminates the
need for external pull-up resistors to hold unused inputs.
The 74LVC(H)162245A is designed with 30 series
termination resistors in both HIGH and LOW output stages
to reduce line noise.

CONDITIONS
CL = 50 pF; VCC = 3.3 V
VCC = 3.3 V; notes 1 and 2
Note
1. CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = total load switching outputs;
Σ(CL × VCC2 × fo) = sum of the outputs.
2. The condition is VI = GND to VCC.
