Product Overview
The SN74ALVCH16841DLR is a 20-bit bus interface D-type latch with 3-state outputs from Texas Instruments. Designed for low-voltage (2.3V to 3.6V) operation, it provides high-speed data latching and bus driving capabilities. The device is housed in a 56-pin SSOP package, making it suitable for space-constrained applications. It features a latch enable (LE) and output enable (OE) control, allowing flexible data flow management.
