Texas Instruments SN54LS169B/SN54S169/SN74LS169B/SN74S169 Synchronous 4-Bit Up/Down Binary Counters Datasheet
The document details the SN54LS169B, SN54S169, SN74LS169B, and SN74S169 synchronous 4-bit up/down binary counters. These devices feature fully synchronous operation where all flip-flops are clocked simultaneously to eliminate output spikes associated with asynchronous counters. They include an internal carry look-ahead circuitry designed for cascading in high-speed counting applications without additional gating.

Questions answered in these manuals
What is the maximum clock frequency for the SN74LS169B?
The maximum clock frequency for the SN74LS169B is 35 MHz.
How many bits does this counter handle?
This device is a synchronous 4-bit up/down binary counter.
What is the function of these devices?
These devices are designed to multiplex signals from four-bit data sources to four-output data lines in bus-organized systems.
Do these devices have three-state outputs?
Yes, the three-state outputs will not load the data lines when the output control pin (G) is at a high-logic level.
What are the applications for these flip-flops?
Applications include Buffer/Storage Registers, Shift Registers, and Pattern Generators.
What are the maximum clock frequencies for the different performance ranges?
The standard and low-power versions support up to 35 MHz and 40 MHz respectively, while the Schottky version supports up to 410 MHz.
