description

The ’ACT16827 are noninverting 20-bit buffers

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.

The 74ACT16827 is packaged in TI’s shrink

small-outline package, which provides twice the

I/O pin count and functionality of standard

small-outline packages in the same printedcircuit-

board area.

The 54ACT16827 is characterized for operation over the full military temperature range of –55°C to 125°C. The

74ACT16827 is characterized for operation from –40°C to 85°C.
