Inverter Gates datasheet and documents for SN74LS03D
Inverter Gates Overview
The SN74LS03D is a quadruple 2-input positive-NAND gate with open-collector outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features an SOIC-14 surface-mount package. The device supports a low-level output current of 8 mA and a high-level output current of -400 µA. Propagation delay is specified at 15 ns, with a maximum static current consumption of 3.6 mA. It functions reliably across an operating temperature range of 0°C to +70°C.
Inverter Gates Feature Summary
- Contains four independent 2-input NAND logic gates
- Features open-collector outputs for wired-logic applications
- Supports standard TTL logic levels
Inverter Gates Applications
- Digital logic circuit design
- Wired-OR bus configurations
- Interface driving for higher voltage loads
Inverter Gates Procurement Notes
Verify the specific manufacturer source and RoHS compliance status before procurement, as legacy components may have varying production histories. Confirm that the open-collector output requirement aligns with the system design, as pull-up resistors are necessary for proper high-state operation. Ensure the SOIC-14 package dimensions match the PCB footprint requirements.
Inverter Gates Selection Notes
Select this component when open-collector NAND functionality is required in a compact surface-mount format. It serves as a direct replacement for other SN74LS03 variants in the same series. Consider the propagation delay and current drive capabilities against the system's timing and load requirements to ensure signal integrity.
Inverter Gates Part Context
This part belongs to the Texas Instruments SN74LS series, which utilizes Low-power Schottky technology to balance speed and power consumption. The SN74LS03 specifically provides quad 2-input NAND gates with open-collector outputs, distinguishing it from standard push-pull output logic families.
Inverter Gates Replacement Considerations
SN74LS03DR is a tape-and-reel variant of the same logical function and specifications.
