Texas Instruments SN74LVC1G373B-Q1 Single D-Type Latch

Texas Instruments SN74LVC1G373B-Q1 Single D-Type Latch with 3-State Output includes one D-type latch to store and control digital data. When the latch-enable input is high, the output follows the data input. When the latch-enable input is low, the output retains the logic level established at the data input.

The TI SN74LVC1G373B-Q1 Latch supports a 3-state output, allowing existing data to remain stored or new data to be written while the output is in a high-impedance state. The device delivers 5.5V-tolerant inputs, supports standard pinouts, and meets or exceeds 100mA latch-up performance per JESD 78. Applications include braking systems, hospital patient care, retail automation, and printers.
