DM74LS491 | 10-Bit Counter General Description\nThe ten-bit counter can count up, count down, set, and load 2 LSB’s, 2 MSB’s and 6 middle bits high or low as a group. All operations are synchronous with the clock. SET overrides LOAD, COUNT and HOLD. LOAD overrides COUNT. COUNT is conditional on CIN, otherwise it holds.\nAll o | TI 德州仪器 |   | |
