74ALVC16374
Low−Voltage 1.8/2.5/3.3 V
16−Bit D−Type Flip−Flop
With 3.6 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The 74ALVC16374 is an advanced performance, non−inverting
16−bit D−type flip−flop. It is designed for very high−speed, very
low−power operation in 1.8 V, 2.5 V or 3.3 V systems. The
ALVC16374 is byte controlled, with each byte functioning identically,
but independently. Each byte has separate Output Enable and Clock
Pulse inputs. These control pins can be tied together for a full 16−bit
operation.
The 74ALVC16374 consists of 16 edge−triggered flip−flops with
individual D−type inputs and 3.6 V−tolerant 3−state outputs. The
clocks (CPn) and Output Enables (OEn) are common to all flip−flops
within the respective byte. The flip−flops will store the state of
individual D inputs that meet the setup and hold time requirements on
the LOW−to−HIGH Clock (CP) transition. With the OE LOW, the
contents of the flip−flops are available at the outputs. When the OE is
HIGH, the outputs go to the high impedance state. The OE input level
does not affect the operation of the flip−flops.
• Designed for Low Voltage Operation: VCC = 1.65−3.6 V
• 3.6 V Tolerant Inputs and Outputs
• High Speed Operation: 3.6 ns max for 3.0 to 3.6 V
4.5 ns max for 2.3 to 2.7 V
7.8 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
• 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 >2000 V; Machine Model
>200 V
• Second Source to Industry Standard 74ALVC16374
†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.
