Output drive is rated 32 mA source and 64 mA sink, letting it drive multiple loads on a shared bus without external buffers. The tri-state outputs allow the latch to be placed in high-Z when the bus is owned by another device. The 74ABT family is BiCMOS, blending the speed of ABT with reduced power consumption. ## Single-latch 9:9 configuration for 9-bit data paths The device contains one independent D-type transparent latch with a 9:9 circuit ratio — nine data inputs map to nine outputs. The latch is transparent when the enable input is asserted; data at the outputs follows the inputs. When enable is de-asserted, the outputs latch the last data state. The 24-SOIC package (supplier device package 24-SOIC) uses a 1.27 mm pitch, which is a standard footprint for SOIC-24 wide-body. The surface-mount assembly is straightforward for reflow processes.","metaTitle":"SN74ABT843DW TI 74ABT D-Type Latch, 24-SOIC, 4.4ns","metaDescription":"Texas Instruments SN74ABT843DW 9-bit D-type transparent latch in 24-SOIC. 4.5-5.5V supply, 4.4ns propagation delay, 32/64mA drive.
