Description

SN74HC08DBR is a Texas Instruments quad 2-input AND gate in the 74HC CMOS family. It provides four independent AND gates: Y1 = A1 AND B1, Y2 = A2 AND B2, Y3 = A3 AND B3, Y4 = A4 AND B4. It operates from a supply voltage of 2 to 6 V (typically 5 V), with CMOS levels, low static power, and fast switching. The device is suitable for general digital logic tasks such as gating signals, clock processing, and other combinational logic functions. The DBR suffix denotes a specific package/version of the part (RoHS-compliant, 14-pin). For exact pinout, electrical specs, and timing, consult the TI datasheet.

Features

Here are the typical features of SN74HC08DBR:
- Quad 2-input AND gates (4 independent gates)
- High-speed CMOS logic (74HC family)
- Supply voltage: Vcc = 2 V to 6 V
- Very low static power consumption
- Standard 14-pin package (DBR) containing all four gates
- CMOS inputs with TTL-compatible levels at proper Vcc
- Outputs capable of driving moderate loads (standard CMOS fan-out)
- Fast propagation delay (typical ~8 ns at 5 V)
- High noise margin and robust operation across the common temperature range for HC parts
- Suitable for standard logic-level interfacing and integration into 74HC08-compatible designs
Note: Exact parameters (propagation delay, input/output currents) vary with supply voltage and temperature; consult the TI datasheet for precise figures.
