Integrated Circuit
TTL − Quad 2−Input Positive NAND Schmitt Trigger
Description:
The NTE74132 is a quad 2−input positive NAND Schmitt trigger in a 14−Lead plastic DIP type package.
Each circuit functions as a 2−input NAND gate, but because of the Schmitt action, it has different input
threshold levels for positive (VT+) going and for negative going (VT−) signals.
This device is temperature compensated and can be triggered from the slowest of input ramps and still
give clear, jitter−free output signals.
