Texas Instruments SN74AHC573/SN74AHC573-Q1 D-Type Latches
Texas Instruments SN74AHC573/SN74AHC573-Q1 Octal Transparent D-Type Latches are octal transparent D-type latches designed for operation with a VCC range of 2V to 5.5V. The Q outputs follow the data (D) inputs when the latch-enable (LE) input is high. The Q outputs are latched at the logic levels of the D inputs when LE is low. The Texas Instruments SN74AHC573-Q1 devices are AEC-Q100 qualified for automotive applications.
Features
- Wide operating range of 2V to 5.5V VCC
- 3-state outputs directly drive bus lines
- Latch-up performance exceeds 250mA per JESD 17
Applications
- Servers
- PCs and notebooks
- Network switches
- Wearable health and fitness devices
- Telecom infrastructures
- Electronic Points of Sale (POS)
