74ALVCH16245
Low−Voltage 16−Bit
Transceiver with Bus Hold
1.8/2.5/3.3 V
(3−State, Non−Inverting)
The 74ALVCH16245 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.
The 74ALVCH16245 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.
• Designed for Low Voltage Operation: VCC = 1.65 − 3.6 V
• 3.6 V Tolerant Inputs and Outputs
• High Speed Operation: 3.0 ns max for 3.0 to 3.6 V
3.7 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
±12 mA Drive at 2.3 V
±4 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 (40 mA)
Substantially Reduces System Power Requirements
• Latchup Performance Exceeds ±250 mA @ 125°C
• ESD Performance: Human Body Model >2000V; Machine Model >200V
• Second Source to Industry Standard 74ALVCH16245

†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.

10. For CL = 50 pF, add approximately 300 ps to the AC maximum specification.
11. 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.
