74LS189 64-Bit RAM With 3-State Output IC – DIP-16 Package 74LS189 64-Bit RAM With 3-State Output IC – DIP-16 Package The 74LS189 is a high-speed 64-bit RAM organized as a 16-word by 4-bit array. Address inputs are buffered to minimize loading and are fully decoded on-chip. The outputs are 3-state and are in the high impedance state whenever the Chip Select (CS) input is HIGH. The outputs are active only in the Read mode and the output data is the complement of the stored data. Features: 3-State Outputs For Data Bus Applications Buffered Inputs Minimize Loading Address Decoding On-Chip Diode Clamped Inputs Minimize Ringing Specifications: VCC Pin Potential to Ground Pin: −0.5V +7.0V Input Voltage (Note 2): −0.5V ~ +7.0V Input Current (Note 2): −30 mA ~ +5.0 mA Voltage Applied to Output in HIGH State (with VCC = 0V) Standard Output” −0.5V to VCC 3-STATE Output” −0.5V to +5.5V Current Applied to Output in LOW State (Max) Supply Voltage +4.5V to +5.5V Mounting Style: Through Hole Package/Case: PDIP-16 Related Document:- 74LS189 IC Datasheet
