At 720 µA typical supply current, the dual timer draws less than many single 555 bipolar parts — the LinCMOS process keeps the quiescent power low enough for battery-backed timing chains where every microamp counts. ## Package and board-fit — SOIC-14 rework and footprint notes 14-SOIC (0.154\" body width, 3.90 mm) with a 1.27 mm pitch — the standard SOIC footprint that reflows on a standard profile and inspects under visible light without X-ray. The supplier device package is 14-SOIC; no exposed pad means no thermal-via array under the part, so a two-layer board handles the routing for most timing circuits. ## Lifecycle and compliance — active, RoHS3, no PCN watch needed RoHS3 compliant, so it ships into EU and UKCA markets without an exemption expiry date to track.","metaTitle":"TLC556IDR Texas Instruments Dual 555 Timer, 2.1MHz, 14-SOIC","metaDescription":"TLC556IDR Texas Instruments LinCMOS dual 555 timer, 2.1 MHz max frequency, 720 µA supply at 3-18 V.
