The 4.6 ns propagation delay (max) sets the data-rate ceiling — the latch can capture and hold data at clock rates well above 100 MHz in a typical 3.3 V system, provided the output load capacitance is kept under the 50 pF the datasheet characterises. At 3.3 V the 24 mA source/sink drive (both high and low) is enough to drive a heavily loaded data bus or a bank of LED indicators directly — no external buffer needed. At 5 V the same drive current gives a wider noise margin on the bus. Surface-mount assembly with the standard JEDEC MS-013 profile; no special bake required for moisture-sensitive level 1 parts. ## Sourcing and compliance posture Sourced through independent distribution channels against a confirmed RFQ. No official second-source cross-reference from TI, but the AC series is widely second-sourced by other logic vendors — confirm pin-compatibility at the BOM level before substituting.","metaTitle":"SN74AC563DBLE D-Type Transparent Latch, 8-bit, 4.6ns","metaDescription":"TI SN74AC563DBLE 8-bit D-type transparent latch with tri-state outputs, 4.6ns propagation delay, 2V-6V supply, 24mA drive.
