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.
The first part number in the series, the 7400, is a 14-pin IC containing four two-input NAND gates. Each gate uses two input pins and one output pin, with the remaining two pins being power (+5 V) and ground. This part was made in various through-hole and surface-mount packages, including flat pack and plastic/ceramic dual in-line.
The 74181 is a 4-bit slice arithmetic logic unit (ALU), implemented as a 7400 series TTL integrated circuit. Introduced by Texas Instruments in February 1970, [1] it was the first complete ALU on a single chip. [2] It was used as the arithmetic/logic core in the CPUs of many historically significant minicomputers and other devices.
A single address decoder with n address input bits can serve up to 2 n devices. Several members of the 7400 series of integrated circuits can be used as address decoders. For example, when used as an address decoder, the 74154 [3] provides four address inputs and sixteen (i.e., 2 4) device selector outputs.
Pure, logic-only gate-array design is rarely implemented by circuit designers today, having been almost entirely replaced by field-programmable devices. The most prominent of such devices are field-programmable gate arrays (FPGAs) which can be programmed by the user and thus offer minimal tooling charges, non-recurring engineering, only ...
Flipper Zero is designed for interaction with various types of access control systems, radio protocols, RFID, near-field communication (), and infrared signals. [6] [7] To operate the device, a computer or a smartphone is not required; it can be controlled via a 5-position D-pad and a separate back button.

Aside from the additional security features that should go with parking barrier gates, electric security gates often offer safety features like sensors that determine when there is an obstruction to prevent the electronic gate from swinging into a vehicle or closing on somebody's hands.
