74ALVCH16244  
Low Voltage 16-Bit Buffer/Line Driver with Bushold  
General Description  
Features  
The ALVCH16244 contains sixteen non-inverting buffers  
with 3-STATE outputs to be employed as a memory and  
address driver, clock driver, or bus oriented transmitter/  
receiver. The device is nibble (4-bit) controlled. Each nibble  
has separate 3-STATE control inputs which can be shorted  
together for full 16-bit operation.  
1.65V to 3.6V VCC supply operation  
3.6V tolerant control inputs and outputs  
Bushold on data inputs eliminating the need for external  
pull-up/pull-down resistors  
tPD  
The ALVCH16244 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.  
3 ns max for 3.0V to 3.6V VCC  
3.7 ns max for 2.3V to 2.7V VCC  
6.0 ns max for 1.65V to 1.95V VCC  
The 74ALVCH16244 is designed for low voltage (1.65V to  
3.6V) VCC applications with output capability up to 3.6V.  
Uses patented noise/EMI reduction circuitry  
Latch-up conforms to JEDEC JED78  
ESD performance:  
The 74ALVCH16244 is fabricated with an advanced CMOS  
technology to achieve high speed operation while maintain-  
ing low CMOS power dissipation.
