The MC74HC1G08DTT1G is a single 2-input AND gate from onsemi in the 74HC high-speed CMOS family. Operating from 2.0V to 6.0V with 7.5ns propagation delay at 5V, it provides the AND logic function (Y = A\u00b7B) in a tiny TSOP-5 (SOT-23-5) package. With balanced propagation delays, \u00b15.2mA output drive, and input clamp diodes, it is ideal for single-gate logic glue in space-constrained designs.<\/p>\n

The output is high only when both inputs are high; for all other input combinations, the output is low. The 2.0V to 6.0V supply range covers 3.3V and 5V logic systems, and the 7.5ns typical propagation delay at 5V provides fast switching. The device is useful for signal gating (one input as signal, the other as enable), condition monitoring (two conditions must be simultaneously true), and chip select qualification. The DTT1G suffix specifies TSOP-5 tape-and-reel packaging rated for -55\u00b0C to +125\u00b0C.","working_principle":"The MC74HC1G08DTT1G implements the 2-input AND function using a CMOS gate structure. The AND function produces a high output only when both inputs A and B are at a logic high level. In CMOS implementation, the AND gate is typically constructed as a NAND gate followed by an inverter, using complementary PMOS and NMOS transistor networks. The output stage is push-pull, providing active pull-up and pull-down with rail-to-rail output swing. Input clamp diodes protect the gate oxide from electrostatic discharge by limiting the input voltage to VCC + 0.5V and -0.5V.","pin_description":"

      • Clock Gating:<\/b> Gate a clock signal with an enable control. Connect the clock to input A and the enable signal to input B. When enable is high, the clock passes through to output Y. When enable is low, Y stays low regardless of the clock state. This is a simple clock gate that prevents clock distribution to unused modules, reducing dynamic power consumption.<\/li>
      • Dual-Condition Chip Select:<\/b> Qualify a chip select with a second condition. Connect the address-decoded chip select to input A and a bus cycle indicator (e.g., read\/write strobe) to input B. The chip is selected only when both the address matches AND the bus cycle is active, preventing spurious accesses.<\/li>
      • Safety Interlock:<\/b> Implement a safety interlock where two conditions must be simultaneously true for operation. Connect a door-closed sensor to input A and a guard-present sensor to input B. The AND output goes high (enabling the machine) only when both safety conditions are met. The hardware AND gate ensures the interlock cannot be bypassed by software.<\/li><\/ul>","alternative_models":"
