74LVCH16245A
FEATURES
• 5 V tolerant inputs/outputs for interfacing with 5 V logic
• Wide supply voltage range from 1.2 to 3.6 V
• CMOS low power consumption
• MULTIBYTETM flow-through standard pin-out
architecture
• Low inductance multiple power and ground pins for
minimum noise and ground bounce
• Direct interface with TTL levels
• High-impedance when VCC = 0 V
• All data inputs have bushold (74LVCH16245A only)
• Complies with JEDEC standard no. 8-1A
• ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V.
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 3.3 or 5 V devices. In 3-state operation,
outputs can handle 5 Volt. These features allow the use of
these devices as a mixed 3.3 and 5 V 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 device 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 bushold data inputs eliminates the
need for external pull-up resistors to hold unused inputs.

power dissipation capacitance per gate VCC = 3.3 V; notes 1 and 2
Notes
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.
