3 Description
The SN74LV540A device is an octal buffer/driver
designed for 2-V to 5.5-V VCC operation.
This device is ideal for driving bus lines or buffer
memory address registers. It features inputs and
outputs on opposite sides of the package to facilitate
printed circuit board layout.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
This value is limited to 5.5-V maximum.

9 Detailed Description
9.1 Overview
The SN74LV540A device is an octal buffer/driver designed for 2-V to 5.5-V VCC operation.
This device is ideal for driving bus lines or buffer memory address registers. It features inputs and outputs on
opposite sides of the package to facilitate printed circuit board layout.
The 3-state control gate is a two-input AND gate with active-low inputs so that, if either output enable (OE1 or
OE2) input is high, all corresponding outputs are in the high-impedance state. The outputs provide inverted data
when they are not in the high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

10 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
10.1 Application Information
The SN74LV540A is a low-drive CMOS device that can be used for a multitude of bus interface type applications
where putput ringing is a concern. The low drive and slow edge rates will minimize overshoot and undershoot on
the outputs. The inputs are tolerant to 5.5 V at any valid VCC. This feature makes it Ideal for translating down to
the VCC level. Figure 5 shows the reduction in ringing compared to higher drive parts such as AC.

10.2.1 Design Requirements
This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus
contention because it can drive currents that would exceed maximum limits. The high drive will also create fast
edges into light loads, so routing and load conditions should be considered to prevent ringing.
10.2.2 Detailed Design Procedure
1. Recommended Input Conditions
– For rise time and fall time specifications, see Δt/ΔV in the Recommended Operating Conditions table.
– For specified High and low levels, see VIH and VIL in the Recommended Operating Conditions table.
– Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC.
2. Recommend Output Conditions
– Load currents should not exceed 35 mA per output and 70 mA total for the part.
– Outputs should not be pulled above VCC.

11 Power Supply Recommendations
The power supply can be any voltage between the MIN and MAX supply voltage rating located in the
Recommended Operating Conditions table.
Each VCC pin should have a good bypass capacitor to prevent power disturbance. For devices with a single
supply, 0.1 μF is recommended. If there are multiple VCC pins, 0.01 μF or 0.022 μF is recommended for each
power pin. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. A 0.1 μF and
1 μF are commonly used in parallel. The bypass capacitor should be installed as close to the power pin as
possible for best results.

12 Layout
12.1 Layout Guidelines
When using multiple bit logic devices, inputs should not float. In many cases, functions or parts of functions of
digital logic devices are unused. Some examples are when only two inputs of a triple-input AND gate are used,
or when only 3 of the 4-buffer gates are used. Such input pins should not be left unconnected because the
undefined voltages at the outside connections result in undefined operational states.
Specified in Figure 6 are rules that must be observed under all circumstances. All unused inputs of digital logic
devices must be connected to a high or low bias to prevent them from floating. The logic level that should be
applied to any particular unused input depends on the function of the device. Generally they will be tied to GND
or VCC, whichever makes more sense or is more convenient. It is acceptable to float outputs unless the part is a
transceiver. If the transceiver has an output enable pin, it will disable the outputs section of the part when
asserted. This will not disable the input section of the I/Os so they also cannot float when disabled.
