Product Summary

The 74HC540N is an octal buffer and line driver. It features the performance of the popular’HC240 series and offers a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit board layout.

Parametrics

74HC540N absolute maximum ratings: (1)Supply voltage range, VCC: -0.5 V to 7 V; (2)Input clamp current, IIK (VI < 0 or VI > VCC): ±20 mA; (3)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (4)Continuous output current, IO (VO = 0 to VCC): ±35 mA; (5)Continuous current through VCC or GND: ±70 mA; (6)Package thermal impedance, θJA: 70℃/W; (7)Storage temperature range, Tstg: -65 to 150℃.

Features

74HC540N features: (1)Wide Operating Voltage Range of 2 V to 6 V; (2)High-Current 3-State Outputs Drive Bus Lines Directly or Up To 15 LSTTL Loads; (3)Low Power Consumption, 80-μA Max ICC; (4)Typical tpd = 8 ns; (5)±6-mA Output Drive at 5 V; (6) Low Input Current of 1 μA Max; (7)Data Flow-Through Pinout (All Inputs on Opposite Side From Outputs).
