Характеристики
SN74HCT540DW, АП12The SN74HCT540DW is an octal Buffer/Line Driver with 3-state outputs. It is designed to have the performance of the HCT240 devices and a pin-out with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit board layout. The 3-state control gate is a 2-input NOR. If either output-enable (OE1 or OE2) input is high, all eight outputs are in the high-impedance state. The HCT540 devices provide inverted data at the outputs. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.
• Inputs are TTL-voltage compatible
• Data flow-through pin-out
• High-current 3-state outputs interface directly with system bus or can drive up to 15 LSTTL loads
• 80µA maximum ICC low power consumption
• 12ns typical Propagation delay (tpd)
• ±6mA Output drive at 5V
• 1µA maximum Low input current
• Green product and no Sb/Br
