12.13. 74LVC14A
12.13.1. Features
• Wide supply voltage range of 1.2 to 3.6 V
• In accordance with JEDEC standard no. 8-1A
• Inputs accept voltages up to 5.5 V
• CMOS low power consumption
• Direct interface with TTL levels
12.13.2. Applications
• Wave and pulse shapers for highly noisy environments
• Astable multivibrators
• Monostable multivibrators
12.13.3. Description
The 74LVC14A is a high-performance, low power, low-voltage Si-gate CMOS device and superior to
most advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as
translators in a mixed 3.3 V/5 V environment.
The 74LVC14A provides six inverting buffers with Schmitt-trigger action. It is capable of transforming
slowly changing input signals into sharply defined, jitter-free output signals.

12.14. LM1117
12.14.1. General Description
The LM1117 is a series of low dropout voltage regulators with a dropout of 1.2V at 800mA of load
current. It has the same pin-out as National Semiconductor’s industry standard LM317. The LM1117 is
available in an adjustable version, which can set the output voltage from 1.25V to 13.8V with only two
external resistors. In addition, it is also available in five fixed voltages, 1.8V, 2.5V, 2.85V, 3.3V, and 5V.
The LM1117 offers current limiting and thermal shutdown. Its circuit includes a zener trimmed bandgap
reference to as-sure output voltage accuracy to within ±1%. The LM1117 series is available in SOT-
223, TO-220, and TO-252 D-PAK packages. A minimum of 10µF tantalum capacitor is required at the
output to improve the transient response and stability.
12.14.2. Features
• Available in 1.8V, 2.5V, 2.85V, 3.3V, 5V, and Adjustable Versions
• Space Saving SOT-223 Package
• Current Limiting and Thermal Protection
