GD7458 DUAL AND-OR GATE IC
The GD74HC58 is a versatile dual AND-OR gate IC, pin-compatible with the standard 74LS58. It integrates one 2-input and one 3-input AND-OR gate, enabling efficient two-level logic implementation. Operating from -40°C to +85°C, this high-speed CMOS IC reduces component count in digital designs while maintaining low power consumption.
Features:
- Low power consumption typical of CMOS technology.
- High output drive capability of 10 LS-TTL loads.
- Faster operating speed compared to standard LS-TTL devices.
- Wide operating voltage range from 2V to 6V.
- Very low input current (1μA Max.) and quiescent current (20μA Max.).
- Excellent noise immunity for reliable operation in noisy environments.
