FEATURES
PIN CONFIGURATION
• Wide supply voltage range of 1.2V to 3.6V
• Complies with JEDEC standard no. 8-1A
• CMOS low power consumption
• MULTIBYTETM flow-through standard pin-out architecture
• Low inductance multiple VCC and ground pins for minimum noise
and ground bounce
• Direct interface with TTL levels
• All data inputs have bus hold (74ALVCH16245 only)
• Output drive capability 50Ω transmission lines @ 85°C
• Current drive ±24 mA at 3.0 V
DESCRIPTION
The 74ALVC16245(74ALVCH16245) is a 16-bit transceiver featuring
non-inverting 3-State bus compatible outputs in both send and
receive directions.
The 74ALVC16245(74ALVCH16245) 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 74ALVCH16245 has active bus hold circuitry which is provided
to hold unused or floating data inputs at a valid logic level. This
feature eliminates the need for external pull-up or pull-down
resistors.

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