HEX SCHMITT-TRIGGER
BUFFER
DESCRIPTION
The UTC U74LVC17A is
a high-performance, low-power,
low-voltage, Si-gate CMOS device and provides six non-inverting
buffers with Schmitt trigger action. It is capable for transforming slowly
changing input signals into sharply defined, jitter-free output signals.
FEATURES
* Operate From 1.65V to 5.5V
* 5 V Tolerant Input/Output For Interfacing With 5 V Logic
*±32 mA Output Drive (VCC =4.5V)
* CMOS Low-Power Consumption And High Noise Immunity
* IOFF Supports Partial-Power-Down Mode Operation
* Latch-Up Performance Exceeds 100 mA

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input negative-voltage and output voltage ratings may be exceeded if the input and output current
ratings are observed.
3. The value of VCC is provided in the recommended operating conditions table.
