SN74HC258
- Wide operating voltage range of 2 V to 6 V
- High-current inverting outputs can drive up to 15 LSTTL loads
- Low power consumption, 80-µA max ICC
- ’HC257 typical tpd = 9 ns
- ’HC258 typical tpd = 12 ns
- ±6-mA output drive at 5 V
- Low input current of 1 µA max
- Provides bus interface from multiple sources in high-performance systems
The SNx4HC257 and ’258 contain four data selectors/ multiplexers to select one of two data sources. All channels are controlled by the same address select (A/B) input, and active-low strobe (G) input. A high level at the G terminal forces all outputs into the high-impedance state. The ’257 has non-inverted outputs and the ’258 has inverted outputs.
