74VCXH16374
Low−Voltage 1.8/2.5/3.3V
16−Bit D−Type Flip−Flop
With 3.6 VTolerant Inputs and Outputs
(3State, NonInverting)
The 74VCXH16374 is an advanced performance, noninverting
16bit Dtype flipflop. It is designed for very highspeed, very
lowpower operation in 1.8 V, 2.5 V or 3.3 V systems. The VCXH16374
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 full 16bit operation.
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 overvoltage tolerant to 3.6V.
The 74VCXH16374 consists of 16 edgetriggered flipflops with
individual Dtype inputs and 3.6 Vtolerant 3state outputs. The
clocks (CPn) and Output Enables (OEn) are common to all flipflops
within the respective byte. The flipflops will store the state of
individual D inputs that meet the setup and hold time requirements on
the LOWtoHIGH Clock (CP) transition. With the OE LOW, the
contents of the flipflops 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 flipflops. The data inputs include
active bushold circuitry, eliminating the need for external pullup
resistors to hold unused or floating inputs at a valid logic state.
Features
Designed for Low Voltage Operation: VCC = 1.65 V 3.6 V
3.6 V Tolerant Inputs and Outputs
High Speed Operation: 3.0 ns max for 3.0 V to 3.6V
3.9 ns max for 2.3 V to 2.7V
7.8 ns max for 1.65 V to 1.95V
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
All Devices in Package TSSOP are Inherently PbFree**
*To ensure the outputs activate in the 3state condition, the output enable pins
should be connected to VCC through a pullup resistor. The value of the resistor
is determined by the current sinking capability of the output connected to the
OE pin.
