74HC/HCT7541
General description
The 74HC/HCT7541 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT7541 are octal Schmitt trigger non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs OE1 and OE2.
A HIGH on OEn causes the outputs to assume a high impedance OFF-state.
The Schmitt trigger action in the data inputs transforms slowly changing input signals into sharply defined jitter-free output signals.
The '7541' is identical to the '541' but has hysteresis on the data inputs.
Features
- Non-inverting outputs
- Schmitt trigger action on all data inputs
- Output capability: bus driver
- ICC category: MSI
