SN74HC541N, Восемь буферных элементов с тремя состояниями
The SN74HC541N is an Octal Buffer and Line Driver with 3-state outputs. This octal buffer and line driver features the performance of the HC240 device and a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit board layout. The 3-state outputs are controlled by a two-input NOR gate. If either output-enable (OE1\ or OE2\) input is high, all eight outputs are in the high-impedance state. The HC541 device provides true data at the outputs.
• High-current 3-state outputs interface directly with system bus or can drive up to 15 LSTTL loads
• Data flow-through pinout (all inputs on opposite side from outputs)
• 80µA Maximum low power consumption
• 10ns Typical tpd
• ±6mA Output drive at 5V
• 1µA Maximum low input current
