description
The
′
ABT16828 is an inverting 20-bit buffer
composed of two 10-bit sections with separate
output-enable signals. For either 10-bit buffer
section, the two output-enable (1OE1 and 1OE2
or 2OE1 and 2OE2) inputs must both be low for the
corresponding Y outputs to be active. If either
output-enable input is high, the outputs of that
10-bit buffer section are in the high-impedance
state.
To ensure the high-impedance state during power
up or power down, OE should be tied to V
CC
through a pullup resistor; the minimum value of the
resistor is determined by the current-sinking
capability of the driver.
The SN74ABT16828 is available in TI’s shrink small-outline package (DL), which provides twice the I/O pin
count and functionality of standard small-outline packages in the same printed-circuit-board area.
The SN54ABT16828 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT16828 is characterized for operation from –40
°
C to 85
°
C.
