The SN74LV161APWR is a 4-bit synchronous, presettable binary counter designed for 2-V to 5.5-V VCC operation. It features an internal carry look-ahead for high-speed counting applications. Synchronous operation is achieved by clocking all flip-flops simultaneously.
Key electrical characteristics include a maximum propagation delay of 9.5 ns at 5V and a count rate of 95 MHz. The device supports mixed-mode voltage operation on all ports and includes features like balanced outputs, over-voltage tolerant inputs, and partial power-down (Ioff) capability.
This counter is available in a 16-TSSOP package, suitable for surface mounting. It offers robust ESD protection, exceeding JESD 22 standards for Human-Body, Machine, and Charged-Device models. Latch-up performance exceeds 100 mA per JESD 78, Class II.
The SN74LV161APWR is well-suited for digital logic designs requiring precise counting and synchronous operation.
