Below you’ll find a non-exhaustive list of the most common 7400-series chips. Click on the IC number of a chip to learn more about its pins, functions, and example circuits. More ICs will be added.

The following is a list of 7400-series digital logic integrated circuits. In the mid-1960s, the original 7400-series integrated circuits were introduced by Texas Instruments with the prefix "SN" to create the name SN74xx.

This is the version approved for the european market. See also the US version IC-746 Pro.

7400, a new multi-mode transceiver offering general coverage receive and c.w., a.m. s.s.b., RTTY, and narrow band f.m. (n.b.f.m.) on h.f. and also the 50 and 144MHz bands. The IC-7400 is the successor to the established Icom IC-746 transceiver (which I reviewed for PW back in November 1998). I remember being very impressed indeed

The IC 7400 is a 14-pin chip and it includes four 2-input NAND gates. Every gate utilizes 2-input pins & 1-output pin, by the remaining 2-pins being power & ground. This chip was made with different packages like surface mount and through-hole which includes ceramic (or) plastic dual-in-line and flat pack.

The IC-746PRO/IC-7400 adopts the 32-bit floating-point DSP and 24-bit AD/DA converter in the IF stage. This combination dramatically improves the precision and the scale of the signal processing, and provides a wide dynamic range from HF to 144MHz band. Selectable filter shapes each in SSB and CW modes

Radio have super DSP. Great receive, display with BIG sharp numbers and ergonomics. Excellent radio. This radio is perfect for contests because almost all major functions are at press of button in front of you and no need to dig deep into the menu to …

2023年10月25日 · The IC 7400 is the most widely used logic family in integrated circuits. Initially, Texas Instruments launched the SN5400 series TTL (transistor-transistor logic) chips back in 1964. This was followed by the introducing of the SN7400 series in 1966, rapidly capturing more than half of the logic chip market.
