C485974

Part: MC74HC4851A, MC74HC4852A, MC74HCT4851A, MC74HCT4852A

Type: Analog Multiplexers/Demultiplexers

Description: These devices are pin-compatible analog multiplexers/demultiplexers featuring injection current effect control, making them suitable for automotive applications where input signals may exceed the supply voltage range without affecting the enabled analog channel. The MC74HC/HCT4851A is a single-pole, 8-position device, while the MC74HC/HCT4852A is a double-pole, 4-position device.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be indicated by the Electrical Characteristics if operated under different conditions.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.

1. Measured with minimum pad spacing on an FR4 board, using 76 mm -by -114 mm, 2 -ounce copper trace no air flow per JESD51 -7.

2. HBM tested to EIA / JESD22 -A114 -A. CDM tested to JESD22 -C101 -A. JEDEC recommends that ESD qualification to EIA/JESD22 -A115A (Machine Model) be discontinued.

Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended Operating Ranges limits may affect device reliability.

1. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
