Product specification
Features
- High speed performance
- Replaces 74F189
- Address access time: 8ns max vs 28ns for 74F189
- Power dissipation: 4.3mW/bit
- Schottky clamp TTL
- One chip enable
- Inverting outputs (for non-inverting outputs see 74F219A)
- 3-State outputs
- 74F189A in 150 mil wide SO is preferred options for new designs are fully decoded on chip. The outputs are in high impedance state whenever the chip enable (CE) is high. The outputs are active...
