Additional Details:

The TC74VCX162373FT consists of sixteen D-type latches with transparent operation. When the latch enable (LE) input is HIGH, the Q outputs follow the data (D) inputs. When LE is LOW, the Q outputs are latched and retain their values. The device also features output enable (OE) inputs, which, when LOW, allow the outputs to be active, and when HIGH, force the outputs to a high-impedance state. This output enable function is useful for isolating the device from the bus when it is not actively driving data.

The device is fabricated using advanced CMOS technology, which enables high-speed performance and low power consumption. It operates over a wide temperature range, typically from -40°C to +85°C, making it suitable for use in a variety of environments. The TSSOP48 package offers a compact footprint, allowing for high-density board layouts. With its combination of speed, low power, and flexible voltage compatibility, the TC74VCX162373FT is an ideal choice for high-performance bus interface applications in modern digital systems.
