SN74HC540 OCTAL BUFFERS AND LINE DRIVER

These octal buffers and line drivers feature the performance of the popular ’HC240 series and offer a pinout 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 .

Features

• Wide operating voltage range of 2 V to 6 V
• High-current 3-state outputs drive bus lines directly or up to 15 LSTTL loads
• Low power consumption, 80-μA max ICC
• Typical tpd = 8 ns
• ±6-mA output drive at 5 V
• Low input current of 1 μA max
• Data flow-through pinout (all inputs on opposite side from outputs) 2 Description These octal buffers and line drivers feature the performance of the popular ’HC240 series and offer a pinout with inputs and outputs on opposite sides of the package.
