74LCXH16374
Low Voltage 16-Bit D-Type Flip-Flop with Bushold
General Description
The LCXH16374 contains sixteen non-inverting D-type flip-
flops with 3-STATE outputs and is intended for bus oriented
applications. The device is byte controlled. A buffered clock
(CP) and Output Enable (OE) are common to each byte
and can be shorted together for full 16-bit operation.
The LCXH16374 is designed for low voltage (2.5V or 3.3V)
VCC applications.
The LCXH16374 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
The LCXH16374 data inputs include active bushold cir-
cuitry, eliminating the need for external pull-up resistors to
hold unused or floating data inputs at a valid logic level.
Features
s 5V tolerant control inputs and outputs
s 2.3V–3.6V VCC specifications provided
s 6.2 ns tPD max (VCC = 3.3V), 20 µA ICC max
s Bushold on inputs eliminating the need for external
pull-up/pull-down resistors
s Power down high impedance outputs
s ±24 mA output drive (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 200V
s Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA)
