Frequently Asked Questions
What is the SN74ACT74D and what does it do?
The SN74ACT74D is a dual D-type positive-edge-triggered flip-flop from Texas Instruments. It contains two independent D flip-flops, each with asynchronous active-low Set and Reset inputs and complementary Q/Q̄ outputs. It captures the D input state on the rising clock edge, making it ideal for data registers, frequency dividers, and state machines.
What package and pin count does SN74ACT74D use?
The SN74ACT74D uses a 14-pin SOIC (Small Outline Integrated Circuit) surface-mount package with 3.9 mm body width and 1.27 mm pitch. The 'D' suffix in the part number designates the SOIC-14 package. It is suitable for automated PCB assembly.
What is the operating voltage and temperature range?
SN74ACT74D operates from a 4.5V to 5.5V supply voltage. The commercial/industrial grade supports an ambient operating temperature range of -40°C to +85°C. Maximum propagation delay is 7.5 ns (tPHL/tPLH) at 5V over the full temperature range.
What are common replacements or alternatives to SN74ACT74D?
Compatible alternatives include the SN74HC74D (CMOS, 2V–6V supply), SN74AHC74D (advanced high-speed CMOS, 2V–5.5V), SN74LS74AD (Bipolar TTL, legacy), and MC74ACT74D from ON Semiconductor. For 3.3V systems, consider SN74AHCT74D which accepts TTL-level inputs. All share the same dual D flip-flop logic function and SOIC-14 footprint.
Is SN74ACT74D RoHS compliant and what is its lifecycle status?
Yes, SN74ACT74D is RoHS compliant and lead-free. Texas Instruments lists it as an active product with full production support and no end-of-life notice. MSL rating is Level 1 (unlimited floor life). It is recommended for new designs requiring 5V TTL-compatible dual flip-flop functionality.
