Key Specifications
| Type Number | VCC (V) | Logic Switching Levels | Output Drive Capability (mA) | fmax (MHz) | Number of Bits | Power Dissipation Considerations | Tamb (°C) | Package Name |
|---|---|---|---|---|---|---|---|---|
| 74HCT244PW-Q100118 | 4.5 - 5.5 | TTL | ± 6 | 36 | 8 | Low | -40 to +125 | TSSOP20 |
Key Features
- 3-State Outputs: The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.
- Input Protection: Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
- Wide Supply Voltage Range: Operates from 2.0 V to 6.0 V.
- Low Power Dissipation: CMOS low power dissipation.
- High Noise Immunity: Ensures reliable operation in noisy environments.
- ESD Protection: HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V, CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V.
- Automotive Qualification: Qualified to AEC-Q100 (Grade 1) standard.
Applications
The 74HCT244PW-Q100118 is suitable for a variety of applications, including:
- Automotive Systems: Given its AEC-Q100 qualification, it is ideal for use in automotive electronics.
- Memory Address Drivers: Designed to improve the performance and density of 3-state memory address drivers.
- Digital Circuitry: Useful in general digital circuit applications requiring buffer or line driver functions.
