9 Application and Implementation
9.1 Application Information
The SN74LVC1G32 device is a high drive CMOS device that can be used for implementing OR logic with a high
output drive, such as an LED application. It can produce 24 mA of drive current at 3.3 V making it Ideal for
driving multiple outputs and good for high speed applications up to 100 MHz. The inputs are 5.5-V tolerant
allowing translation down to V
CC
.
9.2 Typical Application
9.2.1 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.
9.2.2 Detailed Design Procedure
1. Recommended Input Conditions:
– Rise time and fall time specs. See (Δt/ΔV) in the Recommended Operating Conditions table.
– Specified high and low levels. See (V
IH
and V
IL
) in the Recommended Operating Conditions table.
– Inputs are overvoltage tolerant allowing them to go as high as (V
I
max) in the Recommended Operating
Conditions table at any valid V
CC
.
2. Recommend Output Conditions:
– Load currents should not exceed (I
O
max) per output and should not exceed total current (continuous
current through V
CC
or GND) for the part. These limits are located in the Absolute Maximum Ratings
table.
– Outputs should not be pulled above V
CC
.
