description

The ’ACT16541 are noninverting 16-bit buffers

composed of two 8-bit sections with separate

output-enable signals. For either 8-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

8-bit buffer section are in the high-impedance

state.

The 74ACT16541 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 printed-circuit-board area.

The 54ACT16541 is characterized for operation over the full military temperature range of –55°C to 125°C. The

74ACT16541 is characterized for operation from –40°C to 85°C.
