SN54HC540, SN74HC540 SCLS007F – MARCH 1984 – REVISED JULY 2022 SNx4HC540 Octal Buffers and Line Drivers With 3-State Outputs 1 Features 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. This arrangement greatly facilitates printed circuit board layout. • • • • • 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) 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 ’HC540 devices provide inverted data at the outputs.

B. C. D. E. F. G. CL includes probe and test-fixture capacitance. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tr = 6 ns, tf = 6 ns. The outputs are measured one at a time with one input transition per measurement. tPLZ and tPHZ are the same as tdis. tPZL and tPZH are the same as ten. tPLH and tPHL are the same as tpd. Figure 6-1.

Each VCC terminal should have a good bypass capacitor to prevent power disturbance. A 0.1-μF capacitor is recommended for this device. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power terminal as possible for best results. 9 Layout 9.1 Layout Guidelines When using multiple-input and multiple-channel logic devices inputs must not ever be left floating. In many cases, functions or parts of functions of digital logic devices are unused; for example, when only two inputs of a triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such unused input pins must not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. All unused inputs of digital logic devices must be connected to a logic high or logic low voltage, as defined by the input voltage specifications, to prevent them from floating. The logic level that must be applied to any particular unused input depends on the function of the device. Generally, the inputs are tied to GND or VCC, whichever makes more sense for the logic function or is more convenient.

All trademarks are the property of their respective owners. 10.4 Electrostatic Discharge Caution This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 10.5 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions. 11 Mechanical, Packaging, and Orderable Information The following pages include mechanical, packaging, and orderable information.
