74VCXH16245
Low−Voltage 1.8/2.5/3.3V
16−Bit Transceiver
With 3.6 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The 74VCXH16245 is an advanced performance, non−inverting
16−bit transceiver. It is designed for very high−speed, very low−power
operation in 1.8 V, 2.5 V or 3.3 V systems.
When operating at 2.5 V (or 1.8 V) the part is designed to tolerate
voltages it may encounter on either inputs or outputs when interfacing
to 3.3 V busses. It is guaranteed to be over−voltage tolerant to 3.6 V.
The VCXH16245 is designed with byte control. It can be operated
as two separate octals, or with the controls tied together, as a 16−bit
wide function. The Transmit/Receive (T/Rn) inputs determine the
direction of data flow through the bi−directional transceiver. Transmit
(active−HIGH) enables data from A ports to B ports; Receive
(active−LOW) enables data from B to A ports. The Output Enable
inputs (OEn), when HIGH, disable both A and B ports by placing them
in a HIGH Z condition. The data inputs include active bushold
circuitry, eliminating the need for external pull−up resistors to hold
unused or floating inputs at a valid logic state.
Features
• Designed for Low Voltage Operation: VCC = 1.65−3.6 V
• 3.6 V Tolerant Inputs and Outputs
• High Speed Operation: 2.5 ns max for 3.0 to 3.6 V
3.0 ns max for 2.3 to 2.7 V
6.0 ns max for 1.65 to 1.95 V
• Static Drive: ±24 mA Drive at 3.0 V
±18 mA Drive at 2.3 V
±6 mA Drive at 1.65 V
• Supports Live Insertion and Withdrawal
• Includes Active Bushold to Hold Unused or Floating Inputs at a Valid
Logic State
• IOFF Specification Guarantees High Impedance When VCC = 0 V*
• Near Zero Static Supply Current in All Three Logic States (20 mA)
Substantially Reduces System Power Requirements
• Latchup Performance Exceeds ±250 mA @ 125°C
• ESD Performance: Human Body Model >2000 V;
Machine Model >200 V
• Pb−Free Package is Available*
*NOTE: To ensure the outputs activate in the 3−state condition,
the output enable pins should be connected to VCC through a
pull−up resistor. The value of the resistor is determined by the
current sinking capability of the output connected to the OE pin.

7. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGH−to−LOW (tOSHL) or LOW−to−HIGH (tOSLH); parameter
guaranteed by design.
