IDT74LVC16245A
FEATURES:
• Typical tSK(o) (Output Skew) < 250ps
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• VCC = 3.3V ± 0.3V, Normal Range
• VCC = 2.7V to 3.6V, Extended Range
• CMOS power levels (0.4μ W typ. static)
• All inputs, outputs, and I/O are 5V tolerant
• Supports hot insertion
• Available in SSOP and TSSOP packages
DRIVE FEATURES:
• High Output Drivers: ±24mA
• Reduced system switching noise
DESCRIPTION:
This 16-bit bus transceiver is built using advanced dual metal CMOS
technology. This high-speed, low power transceiver is ideal for asynchro-
nous communication between two busses (A and B). The Direction and
Output Enable controls are designed to operate this device as either two
independent 8-bit transceivers or one 16-bit transceiver. The direction
control pin (DIR) controls the direction of data flow. The output enable pin
(OE) overrides the direction control and disables both ports. All inputs are
designed with hysteresis for improved noise margin.
All pins can be driven from either 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mixed 3.3V/5V supply system.
The LVC16245A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
