The SN54LVC573A octal transparent D-type latch is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVC573A octal transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation. These devices feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, input/output (I/O) ports, bidirectional bus drivers, and working registers.

Reference designs

TIDA-010132 — Multichannel RF transceiver reference design for radar applications

This reference design, an 8-channel analog front end (AFE), uses two AFE7444 4-channel RF transceivers and LMK04828-LMX2594-based clocking subsystem which can enable designs to scale to 16 channels or more. Each AFE channel consists of a 14-bit, 9GSPS DAC and a 3GSPS ADC that is synchronized to (...)
