Product Preview
Low-Voltage CMOS
Octal Buffer
Flow Through Pinout
With 5 V−Tolerant Inputs and Outputs
(3−State, Inverting)
The 74LVC540A is a high performance, inverting octal buffer
operating from a 1.2 to 3.6 V supply. This device is similar in function
to the MC74LCX240, while providing flow through architecture.
High impedance TTL compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved
switching noise performance. A VI specification of 5.5 V allows
74LVC540A inputs to be safely driven from 5 V devices. The
74LVC540A is suitable for memory address driving and all TTL level
bus oriented transceiver applications.
Current drive capability is 24 mA at the outputs. The Output Enable
(OE1, OE2) inputs, when HIGH, disables the outputs by placing them
in a HIGH Z condition.
Features
Designed for 1.2 to 3.6 V VCC Operation
5 V Tolerant − Interface Capability With 5 V TTL Logic
Supports Live Insertion and Withdrawal
IOFF Specification Guarantees High Impedance When VCC = 0 V
24 mA Output Sink and Source Capability
Near Zero Static Supply Current in All Three Logic States (10 mA)
Substantially Reduces System Power Requirements
Latchup Performance Exceeds 250 mA
ESD Performance:
Human Body Model > 2000 V
Machine Model > 200 V
These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant

11. CPD is used to determine the dynamic power dissipation (PD in mW).
PD = CPD * VCC2 x fi * N + S (CL x VCC2 x fo) where:
fi = input frequency in MHz; fo = output frequency in MHz
CL = output load capacitance in pF VCC = supply voltage in Volts
N = number of outputs switching
S(CL * VCC2 x fo) = sum of the outputs.
