Texas Instruments (CD74HCT193E) Binary Synchronous Up/Down Counter, 22 MHz

Binary Synchronous Up/Down Counter, 22 MHz, 4.5 V to 5.5 V, DIP-16 Product Overview The CD74HCT193E is a 4-bit high speed CMOS presettable synchronous Binary Up/Down Counter with asynchronous reset. Presetting the counter to the number on the preset data inputs (P0 to P3) is accomplished by a low asynchronous parallel load input (PL\). The counter is incremented on the low-to-high transition of the Clock-Up input (and a high level on the Clock-Down input) and decremented on the low to high transition of the Clock-Down input (and a high level on the Clock-up input). A high level on the MR input overrides any other input to clear the counter to its zero state. The Terminal Count up (carry) goes low half a clock period before the zero count is reached and returns to a high level at the zero count. The Terminal Count Down (borrow) in the count down mode likewise goes low half a clock period before the maximum count and returns to high at the maximum count. Two outputs for n-bit cascading Look-ahead carry for high-speed counting Balanced propagation delay and transition times Significant power reduction compared to LSTTL logic ICs High noise immunity Direct LSTTL input logic compatibility CMOS Input compatibility 10 LSTTL Load standard outputs 15 LSTTL Load bus driver outputs Applications Communications & Networking, Industrial Product Information Logic Family / Base Number: 74HCT193 Counter Type: Presettable Binary, Synchronous, Up / Down Clock Frequency: 22MHz Count Maximum: 16 Logic Case Style: DIP No. of Pins: 16Pins Supply Voltage Min: 4.5V Supply Voltage Max: 5.5V Logic IC Family: 74HCT Logic IC Base Number: 74193 Operating Temperature Min: -55°C Operating Temperature Max: 125°C Product Range: - MSL: -
