What are the key features of CD74HC244M96G4?
- 8 non-inverting tri-state buffer outputs with two independent active-low enables allow splitting the octal into two 4-bit groups for selective bus isolation
- HC CMOS family supports 2 V to 6 V supply and 50 pF load drive, enabling direct interface between 3.3 V MCU buses and 5 V peripheral buses
- Unidirectional drive with tri-state outputs prevents bus contention in shared parallel bus architectures including address bus expansion and data isolation
What is CD74HC244M96G4 used for?
The CD74HC244M96G4 is used as an address bus buffer in microprocessor systems to increase fan-out from CPU address pins to multiple memory devices without signal degradation. Its two independent enable pins allow the octal buffer to act as a bus isolator, selectively connecting or disconnecting sections of an 8-bit data or address bus in memory banking and I/O decoding schemes. The 20-pin SOIC package fits tightly in mixed-logic density boards alongside processor and SRAM ICs.

Frequently Asked Questions
How do the two active-low output enables on the CD74HC244M96G4 allow splitting the 8-bit bus into two independent groups?
The CD74HC244M96G4 has two separate output-enable pins: OE1 controls outputs Y1 through Y4, and OE2 controls outputs Y5 through Y8, so by asserting only one enable at a time, designers create two independent 4-bit tri-state sections from a single IC, enabling time-multiplexed or banked 4-bit bus segments in parallel interface designs.
What supply voltage range does the CD74HC244M96G4 support, and can it interface 3.3 V logic outputs to 5 V bus lines?
The device operates from 2 V to 6 V; when powered at 5 V it accepts 3.3 V CMOS inputs (VIH ≥ 3.5 V at 5 V supply is not directly met by 3.3 V CMOS outputs), so for clean 3.3 V to 5 V interfacing the device should be powered at 3.3 V with the outputs driving 5 V-tolerant inputs, or a dedicated voltage translator should be used.
How many load capacitances can the CD74HC244M96G4 drive simultaneously, and what is its maximum output current?
Each of the 8 outputs is rated for a 50 pF load capacitance and a maximum sink current of 5.2 mA at 5 V supply, allowing each output to drive one standard CMOS input plus typical PCB trace capacitance without violating VOL specifications, and the device can drive all 8 outputs simultaneously without thermal derating at room temperature.
Is the CD74HC244M96G4 compatible with 74LS244 in existing parallel bus designs?
Yes, the CD74HC244M96G4 is pin-compatible with the 74LS244 in the 20-pin SOIC footprint; its HC CMOS inputs accept 74LS VOH levels (typically 2.7 V), making it a drop-in upgrade that replaces bipolar LS logic with CMOS outputs offering lower quiescent current (less than 1 µA versus approximately 35 mA for LS) and higher output drive symmetry.
For a compact PCB, how does the 20-pin SOIC package of the CD74HC244M96G4 compare in footprint to the equivalent DIP package?
The 20-pin SOIC occupies approximately 78 mm² of PCB area (7.5 mm × 10.4 mm body), roughly 3 to 4 times smaller than the 20-pin DIP (10.16 mm × 26 mm), and uses surface-mount pads rather than through-hole vias, freeing routing layers on high-density boards and reducing assembly cost per unit.
